Ladies please give your honest opinions.(long)

I'm 20 years old and my boyfriend is 27, I'm very mature for my age and we've been together 8 months now. In March we found out I was pregnant, and do to a bunch of drama and stress I allowed I ended up getting an abortion, not thinking about what I wanted or my feelings, but his feelings, my mothers and my moms family. I went through a lot after that, and he's been nothing but great(so I've thought) I'm not the kind of woman to go rough my mans phone or any of that because I trust him. But, he had been acting strange for a while, and it was just more so him sending late messages next to me when I would be over, then kind of turning around after he would send them and ignoring me like I wasn't talking to him. He always says he gets group texts, which is true, but usually when they are texting in a group it beeps multiple times, and he wouldn't be sending a long message. So, 2 days ago I was over his house, and I was playing saying "let me see your phone and check them locations" so he gave it to me and I already know the code, so I decide to read some messages.. I see a bunch of "good morning babe" messages to other women, and he was talking about sex with other women(not together) but as a general subject like "most girls like to get bussed on their back, and you're having boring sex lol" and all I did was give him his phone and played it off and said I had to go to work.. I later told him and he was apologizing and everything and asked me to come over... So I did because I just didn't want to be that upset, so the next morning I still had it on my mind and he said you didn't really read them because it was really a bunch of gets and byes, so I took it again and I saw may 29th, he texted a girl "I want to be in your pussy I miss it baby I want to feel that pussy again" she saying she misses him, he says bar don't be mad I haven't spent time like that with you I'm sorry, I've just been busy etc... & I started reading them out loud to him and he snatches his phone, saying no I'm not going through this again. So I cried and left, he just kept texting and calling saying it meant nothing and all this.... It hurt me bad.. Then I went over again so he try's to flip it and ask to see my phone so I let him, he gets mad because I was texting my guy friend about hanging out... But that's all he found, so he kept trying to go off on me like I was a bad person and he wasn't... Then I grabbed his phone again he changed his code I said why, he says "so now you ask if u can go through it"😒 this has all happened in the last couple days I just don't know how to feel... What is this really? And he says he loves me and all that and saying he wants us to forget about it all, but I need to grow up and not go through his phone and all that and trust him... But am I really wrong? What do I do or think.... Because how can I even look at him and he told a female a week ago he wanted to feel her pussy again!!!😞
