Here's the backstory. My girlfriend (23) (I'm 25) and I have been dating for 3 years now but due to life events we currently are living 5 hours apart so we don't get to see each other as often as we'd like but are willing to stick it out for another year. We had a pretty healthy sex life up until the point where we had to move apart. After the move, we would only see each other maybe 2-3 weekends a month which sometimes resulted in us not having sex. It's important to note that she isn't a  very sexually driven person, so on weekends where we wouldn't have sex she'd say something to the extent of she wasn't in the mood for that at the time. We would then both agree to stop and usually end up going  to bed or watching Netflix or something. Sometimes we'd go 2, 3, or even more than 4 weeks without being intimate with each other. It's also important to note I'm a pretty sexually driven person myself, so  sometimes she'd feel bad that it had been so long and we'd do it just to do it and both of us would feel soooooo much better and closer to each other.

However these gaps started to become more and more common the longer we are apart and even asking for pictures would turn into a disagreement of some kind. She said from the start that if I ever needed to get it off she was more than okay with it, but asking for help instead of using porn seemed only to be causing more problems.

So to spice things up we decided to buy a vibrator and some other sex toys for the next time we were together, I sent them to her place so she could take a look at them before we used them as she was nervous about it and had never seen or used one before. We agreed that we'd use them together which is why we ended up buying the toys that we did.

Before this past weekend it had been 4 weeks since we've seen each other, nevermind each other naked. We had talked all week about the possibility of getting that Marvin Gaye sexual healing on,  which she admitted turned her on when we talked about it. The day before I arrived she decided that she was in the mood and couldn't resist trying out the vibrator. Without even mentioning it to me so  I could at least share and enjoy the moment with her  and get off myself too she just went ahead and used it. Even though we decided it was for both of us to enjoy.

When I asked her if she was still in the mood this past weekend she admitted she used the vibrator and no longer wanted to have sex. I got quite upset saying it had been over a month for me, and that I held back from doing anything until we saw each other because we had agreed to use the toys together and get each other off once we finally were together again. It escalated into a larger fight and she ended up throwing my phone at me cutting open my forehead. I ended up packing my things right away and left to stay with a friend who lived close by before driving home in the morning.

AITA for that?
