We broke it off but then…

So a few months back I matched with a guy on Facebook’s new dating-forum. We decided to meet up shortly after. We went for a drive and had very good talks. We seemed to have similar values and goals, and he followed up the same night, asking to see me again. He made it clear that he is very busy at the moment with studies and work. He got of work one Sunday and we were supposed to meet for the second time. His boss who is the only other employee at his job had a chold sick so he cancelled. I got annoyed since I had just spent time getting ready, and I expressed this. Later we talked it out, and I acknowledged that I could have been more understanding to his situation. The next time we were supposed to meet we made plans, and again something came up, and he first told me he would call in an hour to confirm. When an hour and a half passed I called him 3 or 4 times without response, for him to later text saying he doesnt believe he’s able to give me whar I need.

Now its been a while, and we since then unfollowed each other on Instagram, but some days ago I requested to follow him just to see what would happen. It took him 5-7 days to accept, and at the same time request to follow me. What confuses me now, is that a few hours after I accepted his request he removed me as his follower and quit following me. My girlfriends believe he just wants attention since I didnt DM him. But I’m not sure.
