Wife Said She's Done - Pt. 2 ..and Still Hopeful

[OneDay]

Im not doing well today. WAS went out last night and I did not ask her where she was going, with who or what time she was going to be back. Nor did she offer her plans to me. Before I left with the kids, I told her goodbye and to be careful tonight. I did not hear or try to contact her all night. I received a txt at 4:00am saying she was spending the night at her girlfriends. (which she probably was) She came home this morning and acted as if everything was just fine. But I was not fine, I was upset and I think I let is show a bit.

I didnt talk much or ask any question about her night. She talked to the kids, but thats about it. She did ask me "Whats Wrong" as to which I replied "Nothing" with a smile. After a few hours I told her I had some errands to run as to which she replied a very snarky OK.

I was gone for no more than 15mins and I recieved 3 texts from her asking why I was so angry, Whats wrong with me and that Im taking off for the weekend and she cant even get 24 hours with me taking off.(she's been out 3 times in 5 days) I replied back nothings wrong I just need to get alot things done before my trip and today is my only day.

After that I got the "Hey, we need to talk tonight after the kids go to bed" Dammit man. I am soo nervous about this. I think Im going to say the wrong things and spill the beans. What If she mentions, your always taking off etc etc. What if she brings up your acting different, what do I say to that. (I want to say Im getting a life and detaching from you, but I know thats not the right thing to say) I am so bad with confrontation. HELPPPP!
