<human>: So my girlfriend and I have been together for four years. We started dating freshman year of college and ended up living off campus together senior year. Now we're both out of college and are both doing seasonal work travelling to different places.

Ever since my girlfriend went away to her current job we've both been feeling like there's something wrong. She's currently back home with me for the holidays. We've discussed it and there is seemingly no reason to feel this way at all, but we both feel it. Something is just... different. I straight up asked if there was anyone else and she said no. (I do believe her).

I've been trying extra hard to be nice and loving, but she doesn't seem to be putting in the same amount of effort. I'm thinking maybe it's all in my head and I'm just over analyzing the situation because I'm freaked out about losing her?

Here's the kicker though. She's going across country to a new three-month long job and I'm currently staying with her parents until I leave to go on a six-month backpacking trip. This means we won't see each other for about 9 months.

Her mom is totally willing to let me stay with them for the time being until my trip and was the one to initiate the idea in the first place. But my girlfriend is telling me that she feels weird about me staying there while she's gone. She knows I have family issues and that I would absolutely HATE to have to go back to my dad's house for the time being. I find it strange that she feels uncomfortable with me staying here even though I've got a temporary job lined up and everything.

I don't know what to do here. I want to stay together and I know she wants to as well but why am I still feeling like she isn't putting 100% into the relationship? I'm getting the feeling that she wants to take a break and I don't know if I'm ready for something like that. She means too much to me to just let a 4 year relationship dissolve over seemingly nothing.

What should I do here?

<bot>: Girlfriend of four years is acting strange out of the blue. Not sure how to handle it after already talking about it with her.
