First off who gives a damn what single mommies think. Second don't commit to one and please, in begging you, DO NOT Cohabitate with her. They're insane and if they have a son he will get jealous of your relationship with his mother. I now understand where the term "mother fvcker" came from. Kids don't like you fvcking their mother at all.
If you're like me you'll never really like their kid(s) anyways. Their kid(s) will become basically a burden. It's absolutely miserable and makes you feel like the entire relationship is tainted because of the oppressive existence of her spawn. And when her trash tier job if mothering and disciplining her child in a constructive and healthy manner (or lack thereof) fails and she's mad at the kid(s) and then she starts complaining to you, you're now dealing with her sh1tty attitude because of the behavior her mongrel son that she fostered and in enabled and now you have to talk to the damn kid because his moms so p1ssed and doesn't want to put out. I just told the kid "look dude I am not your dad and I'm not trying to be, but you have it easy, just don't eat in your room, get good grades, clean up after yourself and I'll make sure you have no bed time and will make sure your mom leaves you alone, it's very easy, I'll make it so you can do whatever you want as long as you can stop p1ssing her off because now it's almost like she's getting mad at ME because you won't listen. You're sh1t is affecting my life and my peace of mind. If you don't comply I will encourage your mother to take away your priveleges and leave you to her mercy ". Granted I was kind of understanding because she was extremely inconsistent and way to emotional.
But it is not worth it. Single mothers are insane. Also even just fvcking single mothers, they'll try to lure you in and lock you down and manipulate you to game you into being that kids daddy.
