How should I feel?

So for what ever reason I reached out to my x yesterday we split up on good terms so i just said hi any way he got back to me and said my most current bf reached out to him a few weeks ago and was asking weird questions about me.. like that’s weird cause my most current bf has no clue who my x is unless there is still a picture on fb of him idk. So I called my most current bf and asked him and he with out any hesitation said no why would I do that. But I’m thinking what would my x make something up like that. My most current bf has been really weird lately towards me and kinda controlling so idk how to feel at this point
