Am I wrong?

[Arrowslinger]

When my GF of seven years refers to the car, truck, house, dishes, etc. as HERS in general conversation to anyone.

Am I wrong to feel bad?

I do live in the house she bought, but cars, furniture etc. has been bought with me here, although major purchases are not "together".

Probably a stupid question?

Um...if she paid for it, I would make the conjecture that they are in fact hers, and therefore she has the right to claim them as such.

Don't give it a second thought.

I think the rule is that after living together, everything becomes collectively owned. So if she says to someone, "We'll take my car" don't worry. Cause you can say to someone else, "I'll pick you up. We'll carpool in my car", be talking about the SAME car she was, and still be right.

It's sort of a "Mi casa es su casa" situation.

Right or wrong RARELY apply to matters of the heart. You should confront anything that will build to resentment if left untouched. The fatct that you are asking the opinion of strangers implies that it bothers you. Tactfully bring it up, casually even, do it jokingly, before you guys end up in a fight over something you both might think is silly if addressed.
