Search Results: ex boyfriend is hanging out with his ex

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?
