she just doesn't want to admit you're right ;)

You know, if I found something like that in my man's car, I'd be wondering... but I wouldn't be jumping to conclusions like that. Tell your girlfriend she'll get farther by asking whose it was CALMLY, first. I don't blame you for putting your mother on the phone to clarify. If your girl won't listen to you, how else can you prove it?

what a bitch

She's on her period

I would divorce her. sounds insecure and annoying.

just another dumb bitch

well at least you aren't a cheater or a liar :)

OP's wife definitely has issues. Doesn't necessarily mean OP did something. Maybe she had a previous partner who cheated on her, so when something like this happens, it's kind of like a psychological reflex - a conclusion she jumps to based on prior experience. And then, like others have said, when she's been proven wrong - because she's unable to admit it, she calls OP an "asshole" instead. OP should tell her how he feels about it - about the accusation, and also about her reaction after being proven wrong. I'm not saying doing something rash or irrational - but the fact that she can't trust him, means that there's something not right.

Your wife is an idiot.

guilty conscience, I would of believed my husband when he told me it was his mom's the first time he said it.
