<human>: My girlfriend of 8 years has trust issues and accuses me (or implies that I am) of cheating. It happens once or twice every few months. I've never cheated and rarely talk to other girls and I feel her trust problems are unwarranted. 

It's been worse now that I've been living 4 hours away in a house with two other attractive girls (it's work housing, I didn't choose to live there. It's provided for us.) I understood her problem initially, although she has met both and really seems to like both.

I'm really getting frustrated and want to bring it up but am having an anxiety attack thinking about it. It makes me really upset that She's this jealous and I've done nothing. She thinks jealousy is healthy for a relationship and I feel the exact opposite.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: gf of 8 years accuses me of cheating but I've never come close. How do I approach it? It's making me not want to be in the relationship anymore.
