How to cut him off..

okay so my ex & I have been messing around on & off for 5 years .. we dated for 4 months. I’ve known him for a year though before we dated .. I was 15.. he was 18.. I’m now 21.. he’s 24. but anyways we dated for 4 months. & we did have sex. it was amazing. he ate me out & was the best head I ever had. & it didn’t work out.. he played me .. made it seem like it was fault.. & idk.. we stopped talking for a year.. then he came back into my life & we hung out & hooked up. then would stop talking to me & so on. & has been the same for the past 5 years .. he makes me feel guilty when I don’t see him.. when I try saying no .. & like we hookup everytime.. .. that’s all we do.. but his dick game is soooo good. 🥵🥵 Around a year ago.. I found out I was pregnant.. it was his kid .. only one I had sex with.. & I wouldnt tell him for awhile .. & then I told him .. he was excited .... a couple months later .. I miscarried.. I was upset.. but happy.. even though that sounds TERRIBLE .. I didn’t wanna have a kid w him.. it’s soo bad to say.. recently we just started talking again.. I haven’t gave in on seeing him.. but ever since the pregnancy.. he’s been asking me to move in.. he wants me to leave my job traveling.. & to move in with him .. & start a life .. it seems nice .. because I have feelings for him. Alot still.. idk what to do though.. because I don’t want it to be fake ..
