Thanks everyone for providing an input. It helps to talk to people regarding this stuff. Random20 & Searock, the advice you've given me sounds reasonable. However, basilandthyne has a point. The way I said what I said makes it apparent that I have made it clear that I am going to break up with her when I see her. I guess a part of me thinks she could do better if I gave her another chance and by making it clear what I want from her. It feels like its common sense for a partner to do little things here and there. I have to say she is the first girl I've been with who is so closed up and very mellow.
I don't want to sound like the weak one here but I don't want to be heartless either. Me breaking up with her will not make me happy. I will miss her and I like her so much but if that's how it should be it should be then that's what it will be. I understand that I shouldn't have sent her passive aggressive texts but she's done something similar in the past too and I tried significantly hard to keep my cool. It was tough and I didn't lash out & I managed to kinda work it out with her. But, I'm human after all and anyone can get emotional. I was stressed from exams & study and I felt I felt like I was giving and giving and not receiving what I wanted or expected. I'm not a kid and it wouldn't matter much if she got me a present or not as I'm not materialistic but its a little normal for anyone to feel a little disappointed if a greeting is not received from a partner. I know last year with my ex of 9 months, she wished me early in the day and on top of that she bought me many presents even though I never expected anything of her.
Anyways, her last text was about 26 hours ago saying she has no idea what's going on to get that reaction out of me and hopefully I explain it to her when I see her. I'm thinking about texting her back and explaining why I reacted that way without getting into too much detail and tell her that I felt very hurt from her actions & that we should talk in person after she gets back. Does anyone think that I should do this? Even if this does lead to a break up? The problem here is I never had that full conversation with her about what I expect from her in a relationship & if I don't end up doing that and break up, I will feel as if I never fully gave her that chance.
The last thing I want to do is sound like a jerk. I want to be considerate and thoughtful even though this is how I feel about her and I don't want to hurt her feelings.
