Okay this is my first time posting on any forum like this. I've been to forums like this a few times but I've become increasingly worried about my girlfriend. I'd like to say that I am a nice and communicative, though I don't know if that's how she views me or for that matter if that is how I actually am. Anyway, I've been in this relationship for several months with this woman, who I find indescribably amazing, and some things have popped up that have worried me. She is a very shy but kind and caring woman. This however has lead to things that make me feel iffy and worried. Firstly we both go to the same college but are are kept rather busy by our classes to the point where we don't always see each other everyday. I try to at least talk with her or text her at least once a day but she doesn't always respond to any of messages. Now we both have this mutual female friend... who is always with us when my girlfriend and I hang out and when I mean always I mean in the last month we have had maybe 2 to 3 times together where we were just alone. This friend also spends more time with my girlfriend then I do, a lot more. Then when I meet up with my girlfriend and she is there, she constantly complains about our PDA, which mainly consists of holding hands ( I mean it to this is not a case of being unaware of people in our surroundings, we really holds hands and that is it). She has even told us she is sick of it and "can't deal with it." I have asked my girlfriend is she wants to hang out without her and she will say yes but will still show up with this friend anyway. Secondly, she rarely opens up to me and the few time we do hang out end up being when she has a problem which she won't tell me about. These usually consist of either her just holding me for awhile or long walks, which I don't mind if that's what she needs I am more than happy to do that. If we aren't doing those things she generally talks a lot but she doesn't really say anything. However, I know she has at least 2 confidants as she has told me in the past that she trusts these 2 people explicitly and will talk to them. Finally today is the day before my birthday, and we had plans today and for dinner. My girlfriends ex came into town today and not doing to well so she asked me beforehand if it was okay for her to spend some time with her. I said okay as it wouldn't interfere with what we planned on doing. But no she has canceled on me, and I wouldn't have even known if I have i hadn't asked whether should dress up or not for where she was taking me. I love her to bits, but I'm worried that something is going on and she is not telling me and I'm worried about us. I try to ask but I usually receive a sarcastic answer or the subject is changed. I don't want to press but I'm just... I don't know.
