My First & his shenanigans 🤦🏿‍♀️

I KNOW THIS IS LONG PLEASE READ IT ALL THO 😫 Okay I just need some advice. So basically i had a boyfriend he's 20 & im 19, last year around this time & he took my virginity. He's the best bf I ever had to this day & I still miss him foreal. We was together for like 7 or 8 mo but we really liked each other. We never argued we trusted each other all that it was great. One day I saw on his Snapchat he was at this super drunk & he was rubbing on some girl. I texted him to never talk to me again bc I was just so pissed. He kept saying sorry n he was just drunk he didn't mean it blah blah but I wasn't having it. After a little arguing, he decided he wanted to take a break & I was like wtf. He went from wanting to stay together to wanting a break in like a couple hrs. So I just said okay. During the entire "break" I was so confused . I didn't know if he wanted me to leave him alone or still act as his gf. & I even told him that he said to me that I am still his and he is still mine he just wants me to "vibe" with him for a little (he was in the middle of starting this business) so he had a lot on his plate so I probably was stressing him out foreal foreal 😞 but anywho ... he wanted me to vibe which I still didn't understand ... does that mean you can talk to other girls? Am I alllwed to be jealous ... I just didn't know. So the whole time I was just super emotional and thought he was breaking up with me and not actually meaning a break but that's not the case. I feel like I just over reacted w the whole break thing and pushed him away. So we got into another argument and actually broke up. A couple weeks went by we didn't talk at all. I went to this kickback and I was so ducked up I literally couldn't do nothing so I just sat in the corner and watched everyone. His ex (right before me) was there and next thing U.K. HE WALKS IN !!! And walks straight to her and they get super comfortable. So now I'm thinking okay we just broke up now you w her was you cheating? I really don't think he was I just think it was a coincidence that she came back and me and him broke up and boom bc he spent every single second w me everyday how would he even be able to without me finding out. He didn't see me tho I just sat there and watched them. Then like 3 weeks later my birthday came. The morning of my birthday, he texted me hbd and asked me where I was at and if he could come get me. My heart dropped to my ass bc I just wasnt expecting that. So that night he picked me up took me to get pizza and he brought me a gift (these shoes I wanted soooo bad) I was shooketh and so happy and we had sex & just chilled in the car taking for a little. I asked him about the other lil bitch he said it wasn't what it seemed fr it was just a quick thing that just happened which I really don't know what to believe. After that ..... he didn't talk to me anymore. I was confused AGAIN. He said he missed me and all this stuff and nobody could replace me but now he hasn't even tried to talk to me. Like 2 months went by I still missed him so I just put my pride aside and told him I mksssd him . He told me he missed me too but he doesn't understand why I still want him because he's not shit and all that . I'm just like bruh. So nothing really came out of that. I saw him at my friends wedding I said hi to him he said hi back but he did it soooo awkwardly. Thennn recently, he hmu trying to booty call me and that he wanted me but not a relationship but he still wants to fuck and stuff and I will be the only girl he is with in that sense. So I said okay lol so the other day he came and got me we chilled talked had sex and talked some more and he was saying the same stuff that he misses me and stuff and I'm the only girl he gets along with this well and I understand him and we were talking about his business and what I am up to and all that . Now I just don't know if what I did was stupid ? What do y'all think his intentions are? Do you think we will ever be together again? OH SOMETHING IMPORTANT:: when we were bf & gf I asked him how he decided he wanted me and stuff and he said at first he just wanted to have sex with me but when he got to know me and stuff he really liked me and his intentions changed. Is that bad? He's a really honest person so idk but I just want to know what you guys think. Please don't come on here calling me dumb n shit I just need to hear some real shit don't be rude .
