There’s a lot of questioning about what he’s up to, what he’s thinking and feeling. How would it be for you to focus on your own feelings?
Consider what you have control over in this situation, and what is best for you. Since you can’t control anything he does, says or thinks, leave him out of the equation. What makes you feel happiest and most confident? It sounds like you’re no longer having lunch anymore. That’s probably a good thing.
You’ve tried to get things back to normal but it’s clear that’s not possible, at least not right now. So what if you were able to accept that you guys aren’t really friends anymore, that he’s a casual work acquaintance now, and continue to do what is the most healthy choice for you. Doing your own thing for lunch is a wonderful step in the right direction. Accepting that this guy hasn’t treated you well and likely isn’t the kind of person who can be trusted in the long-run might help.
