My wife became a Jehovahs witness about 8 or 9 yrs into our 13 yr marriage and then things started to change in our marriage... I asked her to not have the witnesses at our home because of things they told me about other Christians and I wouldn't have that in my home. Anyway our marriage went down hill over all since then. It wasn't always perfect but that added to the deal.
I grew up without a father and took courses in college to learn about children because I always wanted children and be t he best dad. I have a 1.5 yr old boy an 8 yr old girla and a 12 yr old girl. I absolutely love my children to all heaven. I love my children. I have studied children watch the news of everyday lives of others and try the best to keep my children on top of all issues regarding their education, health and the future for their best interest.
We have been to all the Flroida theme parks in Florida and I strive everyday to love and kiss and hold my children. On the other hand my wife isn't so romantic or affectionate. Everything most women want in a man I am twice as much and need more. A day don't go by that my kids don't get a hug and kiss in the morning and at night.
Since the depression we lost our home in Fort Myers Florida and I moved everyone close to my wife's sisters in Gainesville Florida. Well we didn't have no savings or anything at this point and then my wife was getting depressed and then she just seemed as if she was tired of our entire past. She enver liked the fact that I was a people persona and she was of a hispanic heritage. She didn't trust me and she didn't think married men should ha ve friends of the opposite sex but that also presented a problem with me because I love everyone... I really love people on all levels like friends and family.
Every time my kids and I would be somewhere women would comment on my children... they would talk with me and I would converse all day long whenver and wherever I was. Well Lisa would hear about it and go crazy since my children were there and Lisa would use my encounters as cheating oppportunities. I wanted the best for me and her but she never trusted me and I didn't see,m to care how she felt because I knew I wouldn't cheat on her. She stopped caring about me and it seemed as if we were together just for the kids and then all of a sudden after we moved to Gainesville she said I should find someone else to be with because she was not going to be with me anymore. Physically or emotionally.
Of course then I say OK and start posting web sites looking for friends and she takes and wants to move out with her college aged sister. I am afraid that my children will not be safe with her since she doesn't know whow to keep them safe from harm. She isn't aware of her surroundings and she doesn't and couldn't defend herself much less our children. I want my kids with me more than normal and I guess she wants child support. We live close enough to have joint custody but she wants state help and they say she needs to file for child support. I say I want joint custody.
Can she get child support if I want joint custody? I'm wiling to pay whatever I can to help her as long as she plays by the rules and lets me see them as much as I want when she isn't with them. What should I do. Can she just take the kids and move out? I feel like my life is going to be turned upside down. I want to have joint custody so that I don't have to pay her anything. I'll buy the children anything they need and I'll be more of a parent than she would be.
She actually was baker acted once when we first got married after about 6 months or a year for instability issues. Maybe that issue would help me out. I want everything to go well but I read all too many stories about children and fathers put against each other by the mom. I hear stories of fathers going to jail for issues not of their fault. I am very concerned and want the best for all parties. I need advice badly.

What kind of joint custody do you want? Legal? Physical? Both?
61.046 (14) “Parenting plan” means a document created to govern the relationship between the parents relating to decisions that must be made regarding the minor child and must contain a time-sharing schedule for the parents and child. The issues concerning the minor child may include, but are not limited to, the child’s education, health care, and physical, social, and emotional well-being. In creating the plan, all circumstances between the parents, including their historic relationship, domestic violence, and other factors must be taken into consideration.
(a) The parenting plan must be:
1. Developed and agreed to by the parents and approved by a court; or
2. Established by the court, with or without the use of a court-ordered parenting plan
(17) “Shared parental responsibility” means a court-ordered relationship in which both parents retain full parental rights and responsibilities with respect to their child and in which both parents confer with each other so that major decisions affecting the welfare of the child will be determined jointly.

Can she get child support if I want joint custody? ... I want to have joint custody so that I dont have to pay her anything.
Yes! Even in shared parental time if your income is higher than hers one, you will have to pay child support.
A better idea is you to fight to be the primary custodian.

What should I do.
... and your goal is??

You will need a good attorney to help you accomplish full custody. You will need to show the court that the children will be better off emotionally and physically with you than Lisa. Best of luck to you in your quest to gain full custody.

Your post is very confusing and disjointed, with a lot of extraneous information.

Bottom line. If you and your wife have split, you file for divorce. As part of the divorce you ask for custody. Depending on the level of custody granted to either you and/or your wife, you may also ask for visitation. You may be asked to pay support or she may.

This will all be part of the negotiated divorce settlement.
