Should I stay? Should I go? I need help for real

But it also might be remotely possible that she is just seeking to escape the pressure cooker that is being at home with you and your issues (not saying it's right, just saying if you have PTSD and anger issues it could be difficult).

In my opinion, i think that this is what is happening with her. Don't get me wrong, if she is out with guy friends, that is inappropriate even if nothing is going on. This would violate the part of the vows "forsaking all others..."

I been working on my ptsd doing emdr therapy and things are improving a lot. I’m able to sleep now what has reduced my bitterness and mood swings.

This sounds like good progress for you. Keep working on you, that the only thing you can change right now. You'll keep hearing on here "be the man she would be a fool to leave".

I guess most of my problem with the situation is the fact that she doesn’t recognize her fault. She has said that I pushed her away and she craved to feel wanted but she’s insist that she is not having an affair.
We have become more distant. I was trying to be nicer but just to get even more frustrated to see that she has a better relationship with her phone than she does with me.

It appears you also think you've driven her away. It may take some time for her to realize she doesn't have to avoid you any more before she would consider turning back towards you. It doesn't happen overnight.

I’m a complete loner and I have a lot of trouble socializing. I don’t feel comfortable on bars (I don’t drink) neither on closed spaces or crowds.

Have you always been like this or is this because of your PTSD?

Do you know these people as well? It would be good if you could surprise her by getting a sitter and going out with her. Perhaps you could better gauge what is going on that way?

I know I have lots of work to do on myself but her ambivalence just makes me doubt that things are going to work

Again, don't worry about her, just work on yourself. Try to detach from her and for goodness sake, stop bringing up an A unless you have something solid to base it on. If you go the snooping route and are certain, then you can bring it up. There are plenty of people on this forum who got past an A as well, so in the end it may not matter. IMO, The conditions appear good for something to happen though. If your gut tells you something is up, it most likely is, but you shouldn't voice that.
