Vent 30 weeks 3 days

I’m 30 weeks and 3 days I been depressed contemplating if life is worth it my whole pregnancy my baby daddy called me all types of names we broke things off but kept seeing each other and having sexual intercourse, yesterday his new girl I had no idea he had because he would always say I was the one cheating and he wasn’t doing nothing but “working” and “working on himself” dm me on Instagram and asked me who I was I of course told the truth I’m expecting a child by him she proceeded to send me pictures of them kissing and him hanging out with her 2 kids , he spoils them but hasn’t bothered being in my babies life or asking about her I’ve bought everything worked 2 jobs recently quit one because I can’t stand up for hours anymore and it’s getting painful now . I’m so sad , he texted threatening to call the cops on me because I had told her who I was , we were just together on thanksgiving so it’s crazy to me . He accused me of having “hickies” to try and make himself the victim when I haven’t been messing with nobody else his new girl told me thank you for telling him and she still stayin with him since Christmas is coming up . I’m lost in words I’m only 19 he lied to me and told me he was 25 when we met I was only 18 turns out he’s going to be 36 February . He assaulted me pregnant I ended up on the hospital and I wish I would’ve pressed charges when it happened but I didn’t now I regret it I have no will to live I’m lost .
