Ugh 😒 I don't know why my baby likes to go with this guy that lives with us , I just dislike him so much and I hate when he has my baby boy , but my mom is always behind me saying "leave him , he likes him" and when I take my baby boy away from him she gets mad like what type of shit is that , it just bothers me so much 😡I just don't know what to do?
