Well, not for no reason. For lots of small reasons that seem trivial and insignificant on their own but together indicate that your husband just doesn’t love you as much as you need/want/deserve? Even though he’s a good husband and father in every other way, and probably nowhere near as bad as your friends’ husbands?
Interested in hearing other people’s experiences. (My own is quite long and complicated so I need time to figure out how to explain it before I post about it).
