Babydaddy drama

So I'm 32 weeks and my daughter's father and I were dating before I got pregnant. The moment I got pregnant his family and him quickly disowned me . I went back to my parents house and it's been extremely difficult emotionally to deal with . I feel till this day I was never given the chance nor was my daughter and I accepted . I been extremely nice about the situation and act as if it dosen't bother me and I don't need him or his family . But I been holding in so many emotions. He's there for me and the baby when he chooses to be and rather pays attention to the hoes on social media. He works a lot so I know he dosen't actually chill with females but it still bothers me that me and my daughter were never given a chance of a family . So today he post a Instagram meme of Arthur saying when baby daddies bring a girl home but living with babymomma... Hash tagging chill we just roommates . I don't know if I'm overreacting but I feel so hurt and disrespected because all his friends and family know who I am and I feel like he's basically giving these girls and everyone the idea that it's okay to disrespect me because we aren't together . I have a maternity shoot in two weeks with him and at this point I feel like calling it off 😓 its hard to express my feelings and I just don't know what to do anymore . That's my babygirl
