Ok, this is complicated. I am a 25 year old mother of 4 children, 3 shared with my x-husband/friend. My 3 oldest children reside with their dad. He has had a hard time in life te past few years. He was pretty much fired after getting a DUI with his son in the car.Previously he injured his leg badly at work.He has been a heavy drinker for quite some time now.His DL is suspended and he is on probation.He just got a ticket for driving on suspended and no child seats. On top of this he was fired from his recent job for a reason I won't say. I just want to say this befor I sound like I'm bashing him, he has always provided for our children no matter what and loves them very much. I am not perfect either. He has residential custody of them and calls all the shots.My mom and others think I sould modify custody, I feel afraid for some reason. He just got a settlment from his injury and I only make $8.25 an hour in Kasas and live in a one Bedroom apartment with my fiance and youngest baby girl.Up until a few weeks ago I had not worked in a year or so, my fiance is in the Army national guard and is also having trouble finding work. I would like to be able to move to better my life and employment opportunities as a certified regisered medical assistant but he says no when I work up to asking him. He won't budge. We are friends and I don't want to take his girls. That is not my intension. I just want what's best for them. Am I wrong? What steps do I take from here? I'm ready to move forward and feel I deserve to at this point. I too have made misakes in the past but have leared from them.One more thing, my X-husband says he is going to clean up and do better for himself and the kids. Please help I realize this is very personal but I don't know what to do now.
