Love confusion

So me and my best friend made out a couple of times, and it was like a no strings attached and it stayed that way. We both got back into our relationships and we stopped making out(for obvious reasons). Then we both got out of our relationship for reasons that don’t relate to us making out (no one knows, no one will ever find out) we made out again, then he got back into his relationship and I did too. Long story short I broke up with my bf and he’s still with his girl. And I don’t know if I have feelings for him but I don’t know if I should say anything bc it will ruin the friendship we have but I kinda feel he gets jealous when I talk about things I have done with other guys. And I guess I’m just asking for advice on what the heck I do I genuinely don’t know SOMEONE HELP!!!!!
