Girlfriend said she "needed space"/"take a break"

OK....so here is what happened....last weekend, I went to hang out with her on Friday nite. We both had long weeks (we are both teachers) and we were both stressed. She also was having her period and not feeling good, overall. We also had not seen each other for a while (almost two weeks). She wanted some affection from me but I basically ignored her and had other things on my mind (work/personal problems) which I told her later on that night that they were on my mind. When we got ready to sleep, I turned away from her after she wanted to cuddle and she wanted me to hold her. But I was being a dick and didn't do it.

Fast Foward to the next morning, I was still being weird/dick and she noticed it and told me later that things were weird between us and she told me that maybe I shouldn't stay over on Saturday and I just got angry at the whole situation/talk and I certainly did not help things by getting mad and everything escalated. During the conversation, she told me that she needed space and that taking a break would prolly be best. I didn't understand why or what was going on so I was mad/angry and upset at the whole thing.
Eventually, it ended up being that I should go home since I was mad and she was not feeling me anymore at that time.

I left and she said she would take Saturday to think it over. So after taking a day to think it over, We talked and she said she wanted a break and that we could see each other in two weeks.

BTW, her thoughts on a break was not meant so she could see other people but it was more of a personal/work thing.

Since then though I have talked to her almost every night basically...either through IM or on the phone.

Now the other night, we talked again about us, she said she's got a lot of stress and that we were having issues (not being nice to each other, me ignoring her) and that together it was too much for her and that she needed time to decompress and that she felt like she was not getting that. She also said she has a lot to balance (I think she means Work/boyfriend/Dog/room-mate/family/friends) and sometimes its too much. She's also saying that we'll go to dinner next weekend and "see how it goes" and when I asked what that meant she said she thinks it might be weird because we haven't seen each other in a while...

So I don't know. I know I won't feel weird. I think I'll be nervous/excited to see her. I don't know about her. She said it might be weird for her but she doesn't know. I don't see how it could be.

I'm basically going to start bracing myself for the break-up if thats what it turns out to be.
BTW, I think we have been dating for 3-4months and everything was going fine IMO before this. We are really great together and have a lot in common and sexually everything was good their as well. She always gave me compliments on that area of the relationship. We've also told each other before that we "love" each other and I remember one time she told me that she was "in love" with me. I don't know....I told her the other night that I miss her and I hope we are OK.
