My ex (well sort of. We had adisagreement and then a lot of miscommunication a month ago but didn't officially break up) was in my city 2 weeks ago. I knew this because he told me so. All I said back to that was “oh ok cool”. Now, according to my friends that was his way of trying to open the door because he didn’t have to tell me he was in my city. That clearly went over my head.

So fast forward to now. My friend saw that he was here so I shot him a quick text and said heard you’re here. Since I missed you the last time you were here would you like to grab some coffee? Let me know. Miss you.

Not a single word from him. Just completely ignored me. He’s never ignored me before. The hell? Guess I’m just venting. Feeling kind of hurt right now :/

Enjoy chasing and failing. Move on.

Not true. Bottom line is you blew him off (unintentionally) and then you blew him off. Honestly him blowing you off is kind of to be expected. He's also probably really confused. It's like, "so she didn't want to see me 2 weeks ago but when she sees I'm back now she wants to see me?". It's like what does she want? And I'm not going to come running when she calls just because she asked me to after blowing me off recently. He doesn't want to be made a fool of. If you want to salvage this you need to explain you weren't trying to blow him off you just didn't know he was trying to see you.

So what?

Her (or his?) ex told him "Hey I'm in the city!", he didn't invite her (him) for anything up.

That's what people do. He gave OP bait to see him. He didn't just contact her to say he's in her town because he just felt like it. Instead of OP saying, oh really? Want to grab lunch? She said ok cool aka I'm not interested.

Again, your point is?

The ex placed a weak bait expecting to be invited ecc, the bait didn't work.

He didn't show any real balls nor decisiveness.
