Is husband not paying enough attention to me, am I doing something bad

Sounds like you are in a emotional divorce you say he'd never cheat I wouldn't say never .Personally i think your in the right and he's wrong he's either seeing other women heavily into pornography or just wants to be away from you or really busy with his military gig seems like you need to investigate your computer or his phone or laptop history browser and install heavenly eyes its a key logger and whatever he types in you will get a daily report theres other stuff too but maybe invest in getting a porn blocker K9 blocker is good but can be bypassed by phone and there are security setting you can change on his phone and youll have the password he wont be able to bypass. From what I know when husbands act that way there is something in the background goodluck
