Most Helpful Guy
He's an ex, why do you care? Shouldn't you move on? I mean it's one thing for him to be contacting you every few months, but why did you go and contact him?
On a serious note, I think he's hoping you'll consider being his side girl. That's why he doesn't contact you consistently but just every few months. Every now and then, he gets an itch and then gives you the emotional talk hoping you still have feelings for him and you'll be willing to explore each other on the down low while he stays with his girlfriend.
