I don't understand his thought process?

Long story short, my ex and I went on a trip together a week 1/2 ago with us 2, and then 2 other couples.
Everything seemed completely fine and I thought he enjoyed it there.
We were being low-key flirty

I posted a picture of us on Facebook, and my old roommate texted me about it.
Well my old roommate texted me "so you guys are basically back together! " and my ex saw it and read it out loud
I got really embarrassed and went to go grab my phone and he goes "why are you getting so embarrassed? you know I don't care.."


Fast forward to last Saturday night, when my ex came over to my new dorm to hang out.
We smoked (hold the judging), and I didn't want him to drive home after smoking, and so I kept trying to get him to sleep over (I asked about like 20 times… I know, annoying)

When I walked him to his car, I tried giving him a kiss on the cheek goodbye, and I could tell he was really annoyed, and so he was like "we're not dating" and it turned into this huge argument where he said "I don't have a desire to date you right now", while I brought up the fact that he went on a trip with me.


We haven't talked since last Saturday night.
I texted him Wednesday and he never responded. He deleted me off Snapchat (real mature), but kept me on Facebook and Instagram.


Why would he say that he didn't care if someone assumed we were together, but then turn around not even a week later and say "we're not dating" and all that stuff??

(starting next week, we're going to be playing in the same soccer league once a week for 12 weeks)
Ok… 1. he didn't care that I posted the picture
2. me kissing him on the cheek goodbye never bothered him.

Maybe you should be sending out pictures or reports while you are on a trip like this. Just because you can do it doesn't mean its a good idea. No one needs a blow by blow account of your daily life. The old way to do it is still the best. Wait until the trip is over before you start sending out pictures so you can explain what they mean rather than have someone explaining it t you while you are still on the trip. And if you are supposed to be broken up then maybe a kiss is not appreciated. Different people might react in different ways but even though you had been with him you obviously can't read him and people who go together usually learn to read the signals from the other person and since you can' t perhaps that is why you are no longer together. If you who went with him can' t read his thought processes how do you expect those who have never met him to do so?
