I need help & advice ....

I am currently on my period so this may be why I’m so emotionally confused, but my boyfriend of three years broke it off w me back in August but we officially stopped talking in October .... I’ve tried to move on since then and am talking to another boy ... i like him but I’m not sure if i wanna be fully invested do y’all think i should leap into another relationship to start over and prove I’ve moved on or do i not ....
