Search Results: should i call my ex boyfriend

So my ex broke up with me last month. We were together for 5 years, and made a commitment to each other to always support one another. Like any relationship, things weren't perfect. I've been struggling with finding a job in my field since graduating last year. This has been a topic of debate that has caused some fights between us in the past, but we always ended up making up. About a month before the breakup, my boyfriend started to distance himself from me, picking overtime work on the weekends and not calling me during the week. I knew something was wrong, but I really didn't want to push it. One night, I called him and he pretty much exploded at me. He said we would talk about it the next day as he was too tired. The next day he showed up at my place with my stuff and said he "couldn't handle the stress and more", that he "needed to be alone" and that he was "sorry". I was hurt, and all I could do is cry.

I really don't know what to do if he wants to get back together again (if that happens). I still have feelings for him, but he really hurt me and it makes me wonder how he will be able to deal with major life events in the future. Do you think I should give him a second chance if he comes back?

Basically I think I should break up with my boyfriend because I really don't see a future with him. Not because of HIM personally but more so because of our circumstance (long distance with no specific end point).
I also get anxious and insecure because he hangs out with a past ex (even though I've met her numerous times and they were never serious (never were bf/gf))+ he drinks and puts his arms around everyone (boys + girls) when he does so and I'm not sure how I feel about that when I'm miles away.
But I also know he loves me a great amount. He pursued me a great amount and was insistent that he didn't want to break up even after I moved. He calls almost everyday and his day is basically work and calling me. He only drinks with friends like once every two weeks and used to always take me when he went.

I want to break it off and later on remain friends but whenever I imply anything along those lines he says things like "you don't think I'm worth fighting for" etc. even though thats not really it. I'm afraid that if I break it off he'll resent me and won't ever talk to me. So I was thinking maybe I'll wait for him to break it off eventually but then I'm not sure if i wait til he loses feelings for me he'd be motivated to ocntact me either. So this is my question (title).
