Idk if I’m in love

So my boyfriend and I have been together for a few months now and he told me he loved me pretty early on I didn’t say it back at first but then I said it back and kinda got stuck. Before this relationship I was involved with a close friend of mine we weren’t dating but we would have sex quite often and I believed I was in love with Him. I just knew he wasn’t good for me then I met my current boyfriend who did everything the other guy didn’t which is why I’m with him now and not the other guy. I definitely care about him deeply I just don’t know if I love him yet. I get jealous and everything and think about him but I still get distracted by other guys from time to time. I wouldn’t ever cheat on him for a fact but I just can’t tell if I love him or if I’m afraid to actually be in love again bc the guy before treated me so poorly and I let him.
