Advice about husband

Ladies I need your thoughts....

Me and my husband have been married 6 yrs. We have always had a great marriage. No fighting and arguing and have always been really close. There have been a few times Ive known he has watched porn and we had conversations before we dated ab how I feel ab it. Well recently I've noticed hes started watching it again. He will get up in the middle of the night and watch it. Then complain the next day he's exhausted. He doesn't get up to watch it he gets up bc he's not a good sleeper and then watches bc I'm guessing he's bored. He has a very HARD tiring job so I know he gets physically exhausted compared to mine being a desk job. But sometimes I get tired from dealing with the kids and wish he would get up from watching tv and help. I have been snappy lately bc I've been having these horrible dreams of him cheating on me. I know he doesn't have time to cheat he works 10+ hrs a day then is home right after.

Am I just over reacting??? Or being emotional for an odd reason? What's everyone's thoughts about porn?? I have had soo many of my girls tell me...he's just being a man.
