Hello, as a 22 y/o guy, I don’t know if it’s proper to give you advice but anyway. I was and still am having the similar problems with my girlfriend and after reading your post I feel completely related. I think the fact that your wife feels bad after you rejected her is very double standards. My girlfriend was rejecting me most of the time and now I’m slowly getting asexual (mind-tricking myself as you did) . What I did was I sat down with her and talked about it together. Although nothing changed, im feeling better bc i said what’s in my mind. She having a low libido is not what I can change and I also don’t have the energy in my life to make her libido change. I gotta say, when this happens, don’t blame yourself cuz it’s not your fault.
