Because why should he go to counseling when there is truly nothing wrong. Reddit always jumps to conclusions meanwhile he answered every question there was. People go through phases and if someone seems " off" they're could be plenty of reasons which he addressed, not always cheating. What probably pisses him off right now is that his wife truly thinks he is cheating on him due to a bunch of redditors saying the same " get a lawyer, document everything, grab your children and leave" type of comment without even considering that she is just making herself worried. She even said she trusts him 100%. He hasn't done anything to wrong her and she has no solid evidence at all that he is cheating. Counseling is out of the question for him but maybe she should go to therapy herself. The way the brain works is it tries to always look for patterns and connect the dots , so since he is acting a little out of the norm lately and she's probably been doing a little to much reason on Reddit her brain connected some dots that were not meant to be connected. I don't mean to be offensive at all or sound mean but it's just my opinion.
