Long Time Ex/“Friend”

Bi

So my ex from like 10 years ago has decided to come around again. He has kinda always been there to “check on me” but I’m over it. He told me about 2 weeks ago that if we can’t be together then he’s going to have to move on.... What the fuck does that even mean?! It’s been 10 years and I just got married like 7 months ago! *Nothing sexual has happened betwixt is in like 8 years.*
