<human>: Can you summarize the given text in a few sentences?

Hi guys and gals. I need a bit of advice.

My GF of 8 months has had a petty falling out with her Dad and has asked to move in with me and my flat mates.

I should say that she can be very difficult and easily angered over little and trivial things (she openly admits this as well) and her inability to talk to me or her dad or anyone about things can be the cause of some issues in our relationship.

That said we have an amazing relationship and care about each other very deeply and have spoken about moving in together in the future if the timings and her money situation were where they needed to be.

My issue is I live with 2 other guys, one I have known since the age of three and the other that has only just moved in (as of yesterday) and is a complete unknown entity at this point. They didn't agree to live with a couple although they know I have a girlfriend and she stays around (although the new guy doesn't know her or us yet!).

She moved in briefly when we first moved in with our original house mate and although it was nice it was strange at the same time.

I'd like to help her and make sure she is happy but I am pretty sure the other two would be annoyed to have a fourth person there all the time. And she can be very demanding and pushy when she doesn't feel like she is getting her way.

I feel like I am stuck between a rock and a hard place and know that having this conversation with her will cause some sort of issue due to her short fuse.

How should I deal with this situation?
<bot>: GF wants to move in with me and my flat mates but I am sure they would not be okay with that and I don't know what to do.
