Hola,

My ex and I were together for almost 3 years. We broke up and were amicable. He wanted to get back together about the time I started dating my current BF... So 1.5 years ago about. The problem -- there was no legit closure between my ex and I. We are friendly. We used to hang out amicably (most would say bad idea, I know). But after a bit he ended up asking to stop communicating because he was hurt knowing I was with my boyfriend happily. 

Of course I respected his requests and stopped contacting him... We were still friendly when we saw each other but that's about it. He moved away - a plane ride away. I didn't hear from him for about 9 months. All good right? He eventually gets back in contact says he'd like to be friends, etc.

That was about 4 months ago? Maybe 3, I don't know. So we talk here and there. But he is home and leaving Tuesday. He asked me to get lunch with him to "catch up." I'm not worried about anything happening because he's very respectful of my relationship and I am committed. It probably wouldn't hurt to mention that we broke up two Augusts ago after almost 3 years of being together.

So, Reddit. What do you think I should do? Is it reasonable to meet up with him? Is it unfair to my boyfriend? I am curious about what he's interested in saying and I would like to hear all about his life, but I don't want to hurt anyone in the process. Help, please!
