Sorry it’s long but i need advice

So my boyfriend and i have been together for almost 5years...we got engaged 2years ago but got in a petty argument and he called it off. We took a break for a few months (mainly my choice) because this type of petty break-up thing had happened at least 3-4 times prior.

During that time a friend of mine who is attracted to me as more than a friend pops in the picture mostly business related (he does music and i create the cover art and videos) but we have a history and there’s this connection like soulmate connection that’s hard to explain.

Fast forward to now, my boyfriend and i are slowly working things out again with minor hiccups here and there. Im also still working with my friend and his music. He’s expressed his feelings towards me occasionally and sometimes i cant help but to reminisce on the connection ive felt when im with him and lowkey feel the same.

Are my feelings wrong? Am i the one holding my current relationship back because of these feelings? Are my feelings trying to tell me something?
