so i'm 17, i just turned 17 last month. i'm 7 months pregnant and well, my boyfriend is selfish.. there's so many chances i've given him and it's like he spits in my face after all of them. and later apologizes and i take him back..

first i'd like to start off by saying he completely ruins everything that's supposed to be a happy scene for me. the first trimester of my pregnancy he's made it an absolute hell to live in! we were on and off, and he would drink a lot.. he's threatened me, came to my house and made a show out in the street, he said to me "you better abort i'm telling you right now" at only 8 weeks pregnant, he's cheated on me the first month i found out i was pregnant and gave me chlamydia, the whole nine... i forgave him for it and so did my family..

my birthday: a couple days before he was sent to the psych section of the hospital because he was drunk the night before and his mother called the police on him. he got out a day before my birthday.. that same day, i found his phone in his car, and i was able to guess the password, i know snooping is wrong in a relationship but i knew something was off.. and he had many missed calls and texts from different people, i unlocked his phone and it's full of pictures of girl's a**es! he has a video of a girl dancing in her underwear, many messages telling other girls he cheats on me, and goes to other girls houses and messages with his friends saying how much of a bad girlfriend i am... he called me and i told him i saw everything. that's same day he made his mom come to my house to pick up my phone.. later that day is when he was discharged.. and he blamed it all on me... said i shouldn't have been in his phone, he said i was boring the relationship, and that he needed "excitement"... i had never been so dumbfounded or hurt in my life. my birthday was the next day.. and i didn't want to spend it alone.. so i forgave him.. and we got a hotel room on the beach. it was nice throughout the day but later that night i cried like a baby while he was asleep next to me.

my baby shower: it's coming soon, and one of his "friends" who's disrespected me before messaged me on instagram coming at me all sorts of ways, saying she wanted to fight me and she told me that he doesn't claim me.. and that he's always on her. 

at this point i don't know what to do. i mean, i do and its to leave him, but how do you give up on someone you're going to start a family with?..
