What do I do?

It’s been about 9 months that me and my ex boyfriend of 6 years broke up (we didn’t end on bad terms was just the situation we were in) and about 3 months ago he got into a new relationship and so did I, but recently I can’t stop thinking about him and I feel like I’m getting feelings back for him, I just don’t know if I’m completely over him yet and I kinda feel like I’ve rushed into a new relationship but honestly the guy I’m with is so good to me. Most of my family said my ex wasn’t good enough for me or wasn’t right for me but I feel different about that. I just don’t know what to do help!?
