Would you be pissed off?

[AmIjustMad]

DP works a late shift some nights and on a few occasions has dropped one of the girls he works with home. It isn't on his way home, she lives in the opposite direction to us (normally he would get funny about going out of his way) and it seems to be becoming a regular thing, as in whenever they're on the same shift. I get they finish late (12/12:30 am depending on how busy it is) but before he started working there she would just get a cab.
Last weekend I stayed out and he didn't let me know he'd got home ok until about 1:15, normally he would be home by about 12:30, turns out he had taken her home. After this occasion I told him that it was starting to make me feel uncomfortable, as a one-off ok fine, but not every time. He said he didn't really see a problem but would stop doing it anyway if it made me feel like that. We had this conversation a couple of times and I really thought we had understood each others feelings.
So last night he doesn't get home until 1:10am (bearing in mind he works 5 minutes drive away) he walked in and had a chat about work, didn't mention anything about her. I then asked how did x feel about you not taking her home? Turns out he had again taken her home and stopped off to get something to eat too!
He said because I seemed more laid back about it the last time we had spoken about it he thought I would be ok with it, he then said he knew I would have the hump but not this bad. It seems he feels more worried about what she will think of him by suddenly not taking her home than actually caring about what i'm saying to him. It's like he feels some kind of responsibility for her.
How would you feel about it?

hhhmmm 'he is spending 20 mins max with her not driving' Well considering they work together, why do they need to spend 20 mins together after work!

Nope! I would not like that!

Isnt there anybody else available to give her a lift? Is it just the two of them at work at that time?

Call me cynical.

What would he say if the situation was reversed?

Sorry, but I think pictish and co are giving poor advice. Of course it could be perfectly innocent, it ought to be perfectly fine for him to be kind and give a colleague a lift home at night and anyway, you can't stop your DP having an affair if he wants to have one. But I think it's naive to say the least, not to recognise that this is exactly how many affairs start, so you haven't made "a tit of yourself" at all.

And I think it's natural that your antennae began to wave after the first couple of times. That's called safeguarding your relationship. And I would be more hacked off that he carried on giving lifts after you'd spoken about it and expressed your understandable discomfort, and then he kept quiet about it.

I think you should remain on your guard.

No, I would just think he was being considerate to a fellow worker. Times are tough and having to wait around & pay for a cab would be a pain at the end of a long shift. I used to give a life to a male co-worker many years ago - every day, both ways- I think I mentioned it to my DH but would have been amazed if he had been upset.

If he was "just being considerate to a fellow-worker" then he'd be home much sooner than he has been. They've been turning it into a jolly. Different thing.

I'm not saying he's having an affair. I'm just saying it's naive to believe it could never turn into one.
