I don't want to be in a relationship with my baby's father die to past problems. I allow him to come to appointments, things like that but I've been talking to this guy on a serious level & he's trying to ruin it for me. If I get a text from him & im not around my phone my baby father will reply being super childish. & if he mess this up for me I'm gonna be pissed & sad. I don't wanna stop him from coming around but he's really pissing me off. What should I do?
