Last yr I finalized my divorce. I have a 3yrold daughter and a 6 yr old son with special needs. My ex is clinically depressed, is also suffering from PTSD,he is also transgendered. He has threatened to commit suicide lots of times,mostly informing me that it's all my fault. I've since married my current husband. My current husband is very active in the kids lives. My ex is suppose to get every other Saturday to see our son. I had cheated on him and we both knew that my 3 yr old is the result but he put his name on the BC. Now after it's all finalized he is upset and he thinks that he can force me to run a DNA test.
Also he has chosen to not spend any time with our son. And now my husband has been given orders and we are getting ready to move to Colorado. He knew this as I was up front with him. He is demanding 3 months every summer. I understand that he is hurting but I'm of the mindset that he needs to think of what is best for our son. He has taken no interest in our son's special needs,and thinks being a parent means only playing with your child, not the tough and gritty things. He has hardly any income, and I've only required him to pay for our son and lowered his CS myself,with a lawyer present,and notarized.
Can he force me to take a DNA test? And would any judge knowing that he hasn't been present in anything related to our sons special needs, give him 3 months visitation? Our son told me he is afraid of his fathers temper. I'm not sure what to do, we are moving in 3 months. Please help.
I offeredhim1month,and told him he should try to be more active in our sons life,also told him if he wants nothing to do with our 3yr old to then simply file to give up his rights to her, he has chosen to not to do so. He has in fact done nothing paperwork wise but yet complained. Also WA requires you take a parenting class,he hasn't done so.

WA requires that a paternity challenge be brought within a reasonable amount of time. Three years seems to me beyond reasonable, especially in the circumstances.

AS to how a judge would rule on visitation, its anyone's guess. One would hope that a judge would look at your ex's stability and mental health issues and not allow such a prolonged amount of visitation.
