I don't think this has anything to do with his CF at all, just my though.. I think it is mental either anxiety or depression or as someone mentioned his testrosterone levels, possibility...... Hate to ask this but has been been going to the gym more often, changing this style in any way meaning his appearance ? I am not looking to hurt you, but I've seen this happen more than a dozen times over. Esp. with this FB craziness going on I know of 2 marriages that fell apart from meeting people on FB and they left their current marriages. You just never know? Friendships start out slow and sometimes become more than expected. For you to write he does not even want to be touched that put off a red light in my head. I think men get worse mid life crisis than us. Were still looking to hv flat bellies at 41, and we getting new hairdo's all to be more attractive to our husbands. I wld start snooping around I am sorry but I wld ck his phone, is computer, and IPAD if he has these. I know you all may get mad at me, but this is a serious situation. You just don't say after 8yrs marriage don't touch me, and I don't want sex with you anymore. Good Luck Pat/60
