<human>: Give me a shortened version of the text

My ex left me when I was pregnant. Our child is now 2 years old and I'm still struggling to get over the breakup and understand how I should treat him. 

We have had a complicated relationship that blurs the boundaries of a breakup though he is adamant he doesn't want to be with me. 

There's too much history to try to explain briefly, but basically I'm wondering how I should treat him and what type of dynamic we should have. I hate feeling like the annoying baby mama and as mean as he has been to me I care about him and want to be a positive person in his life.

I am the custodial parent and he thinks I'm really mean because we have argued about his involvement and his lifestyle being all about him. There's no point trying to change him and I'm trying to do the best I can for our daughter myself. But I want her to have a dad.
<bot>: What qualities should a child's mother have to encourage the father to be involved, knowing that he really isn't a super involved dad?
