What to do after a breakup??

I just broke up with my boyfriend of 2 months (I know it’s short but I really do care about him and I feel like we both still have feelings for each other, but we were constantly fighting and there wasn’t trust) now im feeling like it was the wrong decision and impulsive because everyone was telling me that was the right thing to do. I don’t want to chase after him, should I give it time and give him space? How do I get it off my mind? *also, this is my first boyfriend who I also lost my virginity to, so I’m not sure if that’s why I feel so attached
