And if your fiancee were here, I would ask her why she is sticking with you, taking such verbal abuse from you over sex (especially when she has sexual abuse in her past), and WHY she is putting up with your crap. You've tried to stop getting angry at her? Really? Why are you even angry with her in the first place?
Rejection hurts, of course. But so does getting land blasted because you aren't putting out... and you ALREADY KNOW of one very painful issue from her past that may be causing her a great deal of problems. Then you GO BACK to the trough, try again, get rejected again... and get angry all over again!!
So the two of you are emotionally lacerating one another... because you love each other so much?
Well. That makes perfect sense.
I know, you'll say it isn't always like that, you don't fight like that all the time. And I very seriously hope not... that you are fighting like that AT ALL makes my stomach roil.
Yeah, I think counseling might be a really good idea... for BOTH of you. Separately.
