You ignored me when you came back from a trip together. Attitude is very different from before. I've been coaxed before There was no sound after that. Why?

1. That guy has a girlfriend, maybe he just got back, and then you just ...

2. Did this man hear that you had a bad reputation before, and so on ... (I mean, someone might irritate you, not offend you)

3. Travel or what happened to you, he achieved his goal and found you boring; Either you didn't achieve your goal and you were depressed.

I think the first one may be bigger. Personal opinion, ha, a shot in the dark, don't take it personally. Don't pay attention to such people. What's the point? There are many good men. Right?
