OK, i have to put my 2c in here...

1. You are sending your H WAY TOO MANY mixed messages.
2. Your husband needs to be educated about threats to marriage and his home - this woman clearly is one
3. Your husband telling you he doesn't mind if you dated was him ASKING for a FREE TICKET to have sex with the OW. It had nothing to do with you. HE wanted a clear conscience.

4. This is off topic, about the breast implant surgery... I don't know if that's a wise thing to do if you are in com martial arts, if you get hit, it can be quite dangerous for you. I know someone who got in a car accident who had breast implants and its the implants that killed her. The impact caused the implant to rupture etc and things got really ugly.

Anyhow... I read through these two pages and what I see most are you trying to go in two or three different directions at once. This is giving your H a LOT of freedom to cheat on you since you aren't addressing the problem head on.
