Affair

Help you do what? Accept that this girl is going on without you because it didn't mean that much to her?

Whats going on in your marriage that you seek attention from someone at the office?

My marriage is going fine. This girl and I share something amazing. We can talk about anything and everything freely and we still do talk about all. This kind of fun and openess is missing in my marriage. Plus I do care for her alot and I know her before my marriage. She has always been important to me but that I love her was a realisation that happened very late. I just want me n her to be normal and as we are even after everything.

No - your marriage is not "doing fine."

All that closeness that you have with this girl should be how it is with your wife.

At one time, it probably was, so what changed that? (kids, bills, health, work?)

This is a fantasy relationship and will disappear/fade when she marries, if not before, because her BF/husband will not put up with it.

Maybe. But how to make myself understand all this. This situation is hurting me

How to improve things with my wife
I have no kids... My health seems fine and as of now no huge bills as well
Please advise me coz this situation is bad for me and I want to come out of it. Recently I took a transfer to another department as well just to avoid regular meeting with her and more importantly I have started missing her too

Moving departments was a good step.

Look - you have just come crashing down from a high. That takes a toll on us. So let yourself grieve emotionally - then allow yourself to process this. She is moving on. Let her go.

You strayed from your marriage for a reason. You really need to find out why. Perhaps counseling could help you find yourself.

Why don't you ask your wife?
