DH warning me about gossip at work

[winewellies]

Bit of background .. DH works away , it used to be 4 nights a week and recently it has gone up to 5 nights and an occasional 'emergency' got to go in today ...
He has in the past suspected I am having an affair ( I'm not !) Posted on here about it.
We get on okay , both tired and stressed with work , kids and elderly parents etc.
He came home last week and said he needed to warn me that he'd had an argument with a guy at work who had been gossiping about him having an affair and that this bloke had threatened to contact me
I asked him if he was , why would someone think he was, who was the OW supposed to be etc etc ~ he said this bloke was annoyed that DH had been given a project over him , that because he doesn't go out with them after work and goes for a walk or visits his Mother (she lives where he works) that it looks dodgy and that there wasn't a particular woman named .
So now I am watching his every move ! Thinking he was trying to get in first so I would dismiss any contact from this bloke or was he being honest !? and its making an atmosphere
Just needed to vent really - don't know how to handle it

Guilty, hang the bastard

Don't be so dramatic! No one has said hang him, they've said keep your eyes open because this doesn't look good. You may think he sounds like a pure little angel, but women who have been on the other side of this, aren't so naive.

He works a 12 hour day with a 3 hour commute (90 minutes each way). That's 15 hours. So if he goes home he will have 9 hours maximum

Yep I can read. Depends on your priorities I guess. Getting three hours with my family would be better than none so I would (and do commute).

I work in an industry where we frequently work long days with late nights and it's very common for colleagues to stay over night so they "don't disturb the family", "can hit ground running" etc.

Most of them are or have been shagging colleagues at some point or are lazy fuckers who don't want to pull weight with childcare.
