Latest and greatest news on my exciting weekend.
I will start with last Friday an employee asked me to go to lunch there was something he thought I should know about. Proceeded to show me some letters stbxw had stored on her laptop that my employee is currently using.
The letters were dated over a yr ago the week I found out about affair. The letters were written to him about how much she loved him, how special he was blah blah blah. How are kids would love him what a great step mom she would be to his kids blah blah blah.
The hurt and pain from this hit me like a ton of bricks. I had plans to take the kids to my sisters for the weekend. After reading this garbage I sent her a text letting know I would be bye to get the kids at 4 and also to check her email. I texted that it all made sense to me now! I sent a copy of letters
She then started trying to reach me by phone at work and mobile. I just couldn't keep this to myself and wanted her to feel my hurt.
She called and said the letters were a year ago blah blah blah. It had nothing to do with D blah blah blah. I got off the phone and sent her some text with highlights of letter about her wanting to be a great step mom , our kids loving him etc etc..
She tried to call me and I just responded by text. I didn't want to talk to her. I don't want to be her friend
I dropped kids off today at 1pm while she was at store. I passed her on the road and she pulled over to talk, I just kept driving.
She texted me telling me how much she hurt this weekend and knowing how much she has hurt me blah blah blah.
I asked her by text to let me know about settlement in writing I would pick it up tomorrow morning when I take kids to school. She wanted to talk about it. I really don't think I am in a good place right now to even see her face. I am sure there are some DB-ers on here that may have some input.
thx
