Hi everyone, it happens that I’ve been in this rel

Hi everyone, it happens that I’ve been in this relationship with this guy for over a year now close to a year and half. The first year was perfect but the last six months has been bad, more of hell. It happened that in january he was dating another girl who lives in same compound with us. And since then he has been acting strange and somehow if I asked him what happened he’ll say nothing that he’s just trying to pull things together and he needs time to himself since then I started giving him space even if I didn’t make it obvious I was still acting normal. Then it got to a time I finally knew he was dating her and that was the reason why he was acting somehow. Then we broke up, he begged me we came back together and then he still went ahead to the girl, one faithful night I caught them in an almost sex scene damn it was soo annoying I never expected it from him. We broke up for about two weeks he still came back begging that he’s sorry and he’ll never do it again blablabla. I forgave him and he started acting normal to some extent. Then of recent he started acting somehow again I’ve been seeing him going to that girl’s place and if I question him he’ll shout at me and avoid the conversation. Then lately he’s been seeing his ex girlfriend too. I questioned him yesterday but he shouted at me and avoid the conversation again. The last few days I was sick he didnt even bother to care when I needed him the most. It was so gross. I decided to ask for a break from him he didn’t even feel somehow and he said ‘you have the space you want’. I don’t know what to think or what to do right now. It happens he’s my first boyfriend and I’ve showed him I loved him too much so I feel he’s taking a great advantage of that, I’m even scared to loose him it kind of hurts. I dunno what to do. I need advice y’all.
Thank you.
