we've run into each other before...so you know I do understand your plight...I've gone the three months before..heck I've even gone a year if you count pregnancies as h found that a time to stay away..grrrr...nothing like extra hormones for the already hd lady..to then have her h turn her down...
any who...my thoughts are this...what if..you stopped looking at your wife as a "fridgid bitch" simply because she's cold physically? is there a way for you to view her as a warm and loving person who simply isn't physical? does she do nice things for you? does she do anything for you? it is possible however no promises made...that if you stop viewing her as fridgid she may soften up a bit.
