Point of View. Still Hung Up on His Ex?

I been texting this guy back and forth for a while now. We've seen each other a few times.
We went to highschool together but we obv didn't know each other. So a few years later we picked up on the texting

Anyway, he asks me to the movies and everytime he does, last minute he has to do something, something comes up.
He delays his texts once in a while.
Like, I replied to his text yesterday at 1:15 (lunch time) he has an iPhone so it still says delivered… But last night around 8:00ish he complimented his ex girlfriend in a photo on Facebook.

I don't wanna continue to talk to someone who's still hung up on their ex.
Should I start to distance myself and keep my text replies deylayed and short?

Cut him off completely. It sounds like you're looking for a romantic relationship. It sounds like this guy is what I like to call "emotionally unavailable." He is not giving you what you need. It doesn't matter if he is hung up on an ex, or just not an affectionate person in general… What you want is more than he is giving you. You deserve better. Go find it.
