Im just looking for advice 😔

Me and my boyfriend are 2 weeks pregnant. But we have kind of like a complicated relationship. We live together and all, but social media kinds if throws me off, my boyfriend doesnt have me on his Facebook page whatsoever, nobody knows we’re together only close family and some friends of mine. But he constantly talks to girls, i dont read his convos it check his phone cause he calls me crazy whenever i talk about something like that.. and reacts to their pictures, he never reacts to mine or even like them. I don’t either but because he doesn’t and i dont even react to other guys pics! Well thing is i usef to talk to guy friends too when we started dating. But im over that nobody even talks to me because i do tell them i have a boyfriend. He says its better to have our relationship private because that way no one will ruin it . Last week he confesses to goingg to the movies ‘ALONE’ and i dont believe that and im scared what if i got w the wrong person and it will be bad for my baby?💔
