How does "just friends" actually work?

Question

I have recently been reconnected with an ex-bf from 15 years ago. We were delighted to be in touch. I was then shocked to realize I never got over him from all those years ago, and we now are both married with children. I told him how I felt-I was willing to try an affair (I know its horrible, but I have not been myself the past few weeks) and he was not. We saw each other, discussed for closure purposes, and while I told him I don't think I can see him in person for a while we both agreed to stay in touch with email/phone. He specifically asked me to call him/write him. So, the question is, I emailed him on Monday basic, friendly, innocent email. Two days later I have not heard back from him. I assume he is trying to cool things off and is busy with work - my somewhat immature question is that I can always find time to email someone back within a few days. Can someone try and read minds and tell me what is going through his? Should I be worried that we can't even be friends?

I appreciate the the answers. Please don't be judgemental with me, I can't feel worse about this then I already do. Its very rare to feel this kind of connection with another person - I want to keep the connection and not hurt anyone else...so some more sympathetic and less judgemental responses would be wonderful.

Answer 1

I think you should leave it alone. You're married and so is he. He obviously doesn't want anything more than a casual acqaintance. When he feels like it's appropriate, he'll respond. He doesn't want to give you the wrong impression or lead you on so he's chillin' and you should too. Don't do or say something that you can't take back and may later regret.

Answer 2

I wouldnt be concerned with it. You are both happily married..leave the past in the past or someone might end up hurt.

Answer 3

I think he's trying to bury his past for the sake of his wife and children. Shouldn't you?
