What should I do?

I think you should let go. Best for all concerned. No need to bring up old feelings and confusions. You both have lives to live and it seems best they need to be lived without each other's friendship.

If you still like him as a friend, then I would call him and tell him that you're making sure he's okay. Make sure that he understands that you do care about him, but only as far as a friend. If he didn't know you were married, I'd tell him. If he did know, then he should have already known that it wouldn't go farther than that. But, if he truly was a friend, then you should probably let him know that.

Let it go. If you're married, stop pursuing friendships with other men. It's not appropriate. If you still have doubts, tell your husband the whole story and ask him if you should call this other man. You don't "need" to know if he's ok.

For six months u dont speak, n now u go to show that u care where he got lost. I know u like him, but ur marriage is stoppin u, but u wanna remain loyal, so why are u putting urself in the way of a misfired bullet.

Just walk away Hun. I know you feel guilty about hurting him. But just move on (good on you for not cheating) Also learn, don't mix business with pleasure. Take care x

Delete the phone number.

He is fine.

There is no reason to call as it just might lead him on and he get the wrong idea

I'm am sure he is fine and has found himself a GF......U should be more concerned about making your marriage work and not find ways to break it.

baby girl, don't call him. when he calls you, you need to make it clear as you are to us. last thing you want is to give him another false impression.

Don't call him....He is fine. It's been six months. Let him move on.

If he stills has feelings for you, you will confuse him. Let it and him go.

Dont lead him on. I think you shouldnt call him at all if you care about him.
