I am engaged and I don't love him I am still in love with my kids daddy and my kids daddy is still in love with me what should I do even though that my kids daddy is in jail for 2 more years should I wait on him or what because I think if you love somebody you would wait so please tell me if I am going to do the right thing

Well if you are not in love and don't love your current fiancé, then what are you doing with him?

You know what is the right thing to do!

Can you wait 2 years for your ex, the father of your kids?

My advice... get out of the relationship you are in at the moment. Put yourself in the guys position and realise that you wouldn't like to be with somebody who cares for another person. Concentrate on your kids and don't just be with somebody for the sake of having a companion. Good luck and follow your heart!

i am engaged and i dont love him

This is absolutely all you had to write.

do not marry this person. you will not be happy yourself and you will knowingly do something AWFUL to another person who deserves better. Yes, it will be ugly to break off the engagement. But it is needed.

As for waiting for the person you love... well, only you can decide whether that relationship is healthy and loving.

But as for your current relationship, end it. All you are doing is creating an illusion that cannot stand the test of time. It will result in both of you being unhappy. And your fiancée deserves a legitimate chance at finding someone that loves him. Right now, you are in his way.

Do what is right. Walk away. No brainer.
