#1 You're overanalyzing everything, there are very few absolutes in life.
#2 Having sex with your H is probably not going to bring him back nor turn him completely away. But it might be fun.
Listen to Bugsy. She always tells it like it T-I-IS! LOL
I'm am totally an overanalyzer. But I also decided #2 was something I wanted to do, because things were so bad before. I'll put it this way...I've had more action since the bomb drop than I have in the past two years before that.
Do what is right for you. But be happy and content with that choice.
