So ladies, I'm desperate for some advice, opinions and some life experiences when it comes to co parenting!

My son's now almost 6 months old and his father and I are well and truly not together. We weren't together for 90% of the pregnancy and only were together for a few weeks after he was born.

The father has had minimal contact with our son and I have had him full time, which isn't at all the issue, I love my little boy.

So his asked me about having him down a couple of nights and I've said no, for so many reasons.

His never had him overnight alone or even for more then a few hours alone, baby is teething and it's been really tough, he lives in a yucky part of town and of course he does drugs.

I do want him to have a relationship with his son but I want to do it in a way that makes me comfortable.

His response to me saying no was that it's not fair for me to doubt his parenting skills and blah blah but his not letting himself be pushed out and he wants to have him anyway because he thinks he has every right, and he does but the petty part of me just wonders why he does cause he doesn't financially contribute, he doesn't spend time with him, he barely asks about him, he hasn't done any of the hard yards and it's just gotten to me. I don't know where to go from here, I'm confused and uncomfortable thinking about leaving my baby with his dad who can't even calm bubs down when his upset.

Sorry for the huge rant but please, HELP ME!!
