Need Help before I blow a fuse.

[20&lost]

Ahoy, thanks for the input. That is where I am stuck. After reading about "Nice Guys" i wonder if I need to get a backbone and let her know that what she is doing is not going to work for me any more or just GAL,180 and PMA for a while longer. I am tired of felling like the door mat. Somewhere I need to stand up for myself and let her know if that is what she wants then just leave. I did meet with a lawyer the other day and he said to not do anything rash, that is if give her the its is either the OM or me, I need to have proof and then act accordingly. Some days I see positives and then it is back to the same. Her parents were in town this weekend to see my D cheer. My W had not seen them since last December and she took Saturday off to go shopping and was gone for 4 hours. The whole family was to eat together that night. She ordered food but didn't eat and then I found out the next day that she wasn't hungry because she had had a early supper with the OM. This is the first time I have snooped in a long time (found the receipt in her pocketbook). She called me multiple times that afternoon to keep coming up with excuses (lies) why she wasn't home yet.

I just do not know whether to stay the coarse (GAL, 180, etc) or to get a PI, show her the proof and tell her she has a decision to make.
