i can't take this anymore

So I was in an abusive relationship for 2 years. We had our ups and downs. Our ups I will never forget, because they were just so perfect. He made it all seem so real and his love too. We were ttc. And yes I know, how stupid can I be. Well,  I did get pregnant. and that's when he completely changed. He started calling me names, he didn't pay as much attention to me like he would. And plus, my gut started telling me there was something up.. well he was already hitting up girls on his social media accounts. He erased me from them, blocked me, and he never did once put anything about me or our expecting baby. WELL, now I know why.. anyways, I moved out. It's been a couple months already and he's been messaging me everywhere.. on my phone, snapchat, Facebook.. telling me things like... that he will always love me, that I'm the love of his life and I will always be. That he misses me, and tons of other things.. but he hsnt tried anything to fix things.. just texting me things.. and I always end up finding out to what parties he's been going to.. he's been going out every weekend. Drinking, and what not. My friend works where we used to live.. as one of those persons who keep the environment clean.. and he told me that he's seen like 2 or 3 girls already who stay the night with him. And leave the next morning like  at 7 or 8 in the morning and they say bye with a kiss and hug :( why is he being like this? Why is he still looking for me after all he's doing? He thinks I don't know, but I fcking know it all. And I just can't take it anymore. :( he started partying like 2 weeks after we were over forsure. If he's making his life already and moving on, why can't he leave me alone? :( I don't answer him anymore because I was just hurting myself more and more. Ugh. I am so broken still. I was finally forgetting about him, and he keeps looking for me :( idk if he looks for me because he "does love me" or because he just wants me as his second choice :( since I gave him so many chances and I know he took that for granted and thought I'd always be there.. I think I deserve better from his since I'm carrying his child :( I'm sorry for this huge thing, I had to vent 💔
