I just wrote a super long response but it all just got deleted. ARgh!!! I hate that when that happens.
I'll summarize..... I don't agree with the "put your marriage in the box". Not wearing your ring does NOT help your case. You should be portraying that you are STILL her husband and are STILL married and that you are not happy with her choice. NOt portraying acceptance to her or your kids. Should you go out and not be mopey and "have a life", etc? YES! But, it should not be done with single, attractive females. Remember when I was the one saying how the OM made me feel attractive, etc. and how all of you said it was 'cause he wanted something. It's the same way with you. You are a hottie, a "catch", you know it ;)...now take that knowledge and find some guys to hang out or find some personal interests. Screw the river rafting, you KNOW B will come.
