After my H moved in with the OW and started having my two young sons (7 & 4) stay with him every other weekend, I figured I had every right to know who my kids were spending time with.
I was driving by the OW's place of work and went in. She was/is a gm of a retail store. When she walked by me, I said "Excuse me are you the manager?" She extended her hand with a huge smile and introduced herself and asked if I needed help. I took her hand, shook it and calmly said "Nice to meet you. I am Dave's wife. I hope you are having fun with him" She jeked her hand away, dropped a huge pile of papers on the floor and crouched down, scrambling on the floor to pick them up. I calmly turned around and walked out. No confrontation. No yelling or pleading. I just wanted her to have an attractive, calm, intelligent woman's face in her mind when I was mentioned by my H.
And to see her scrambling on the floor on her hands and knees gave me so much satisfaction. As did seeing why my husband went from me to her...He was definitely the "prettier" one in THAT relationship.
