Do you ever just feel like you give you give up on guys?

Lately I've been trying to reconnect with someone that I had such strong feelings for. Because we ended on bad terms while he was still trying to call me everyday to see how I was doing but I never answered. I still really like him and want him to fight to have me back. We were talking and he still says he loves me, I really do love him. I told him that we need to make this work so we don't go on and off again. We have been serious for the last couple weeks. I told him that we should just stay friends 2 days ago because he was telling me I don't like him as much I like other guys(trying to make me feel bad) but I like him way more. He has a Twitter and I don't but I made one that doesn't have my name or picture to see  what he does knowing I don't see twitter. I saw tweets exchanged with a female that he started off a tweet she said about guys hitting her up. They were messing around saying how one didn't text the other back and total obvious flirting these past weeks. It just annoying because I dropped so many nice guys for him because he actually made me feel important and he made sure I wasn't talking to any other guys. I have this thing with this one other guy but he's always so busy with work and I lowkey feels like he's just doing it to play around too. I feel like all the guys I talk to just want to play around with my feelings. I feel like my body doesn't want to be loved by anyone but myself. I just feel alone tbh
