Search Results: im still in love with him

tl;dr- considering keeping in contact with an ex im still in love with. broke up last December, talked once every month since then.

I broke up with my ex a few days before Christmas last year. Basically I'm still crazy about him but I had reasons to end the relationship (he was a good partner, he did everything to try and make it work- it's my seriously ugly personal issues). Since we broke up I've just been obsessing about it but I never showed. He sent a long message on new year's day greeting me and telling me he still loves me. I replied and that convo didn't last long. About last week of January, he called me and we talked for a while. After that call, he sent a lot of messages asking if we could still make it work. I love him a lot but I was so sure that getting back together isn't the right thing to do so I stuck with my decision. I blocked him on Facebook after that because it became harder for me to stop thinking about him. I'd visit his profile a lot. Just two days ago he sent messages on Instagram but he unsent them. Then last night he called and we talked for a few hours. It was a really nice talk and I felt instantly better. It included saying I could call him anytime I need someone to talk to. He said he's still waiting and hoping for something between us. He understands why I ended things with him which I didn't expect because he really didn't do anything for me to act that way.

Anywaynot a day goes by that I don't think about him and I miss him a lot so I've thought about considering calling him every now and then. Would that be unhealthy? I didn't say anything to him about getting back together. We just agreed that we can call each other anytime we want, and I do want to. I just dont know what's right or wrong about this anymore.
