Search Results: ran into an ex

My ex broke up with me a little over a year ago. It was a very unexpected breakup, and he told me he just didn't love me as more than a friend anymore. My heart was BROKEN and it took a while to get over it even though our relationship was only four months long (he was my first love). We had an argument a few weeks after the breakup and I hated him then, and when he (drunk I'm guessing) texted me this past summer a few months later saying "Hi", I ignored him.

We only ran into each other like 2 or 3 times last semester. Had very surface level conversation, but we were completely civil. Lately I've been seeing him nearly every day because he suddenly goes to the gym at the same time as I do. He seems to go out of his way to talk to me. The first time I saw him, I waved and he waved back. Later that same time he came up to me and started rambling and even said he was sorry about my dog (that we literally put down A YEAR AGO) even though we've had conversations since that happened. Then another time, after he left the workout area to grab his stuff, he came back and flashed his sweatshirt that had my grad school (which I just announced my decision for on instagram) on it to say congratulations. by the way, I unfriended him and unfollowed him on everything after the breakup and he still follows me. Anyway, yet another time he came and asked to use the machine RIGHT next to where I was working out and kept talking to me, saying he'd feel so bad if he hit me with the machine on accident.

His birthday is sometime this month and he invited my closest friends (who one of which he hasn't talked to in over a year and the other he randomly texted her on her bday last month) to his birthday on facebook. Like I said, we aren't fb friends anymore so he couldn't invite me even if he wanted to.

Wtf does all this mean? (fyi I'm not interested- also graduating in a month and he still has a year)

My ex and I were really close friends before we started dating. I was hesitant about starting a relationship bc we were about to go study abroad in different countries for 2 months but he pushed for it & believed that we could make it work. We did but he was still insecure because I wasn't very affectionate & often asked me where the relationship was going, what he meant to me, etc. After 8 months he wanted a break bc he felt like his feelings were one-sided, I only saw him as a friend, maybe we wanted different things & time apart would be good. I agreed but decided after 2 weeks that I didn't like an indefinite break, so we broke up. He pushed for us to remain friends (he could hang out & come over to my place bc he still enjoyed my company). Then 1 week later he wanted to cut contact so I deleted him from all my social media. But at a mutual friend's party 1 month later, he kept trying to get my attention even when I tried to ignore him to make sure I had a safe ride home. We saw each other again after 2 months, I said hi first. We caught up, joked around, teased each other. He was still very emotionally open & unguarded with me. I told him that i was planning a trip & he said to reach out to him if I had questions. Then we ran into some of my friends & he made it obvious to them that we had a history, & even video snapchat us (I only found out bc mutual friends asked about it). He gave me a ride home & told me it was nice talking to me again, asked if I were doing ok (yes), and said that we should catch up again, I just said "uh" so he backpedaled & said "oh maybe not". I fb messaged him 2 weeks later to meet up & ask about the trip but he didn't reply. But then at another mutual friend thing a week later, he came up to me & asked how the trip planning was. It's been 4 months since we broke up, honestly I miss being friends & hanging out w/ him but I'm scared that he doesn't want the same. Should I try to reestablish a friendship?
