I am 31 and my g/f is 23. We have been dating for about a year. I left about 3 months ago to go to Europe, prior to leaving we spent every day together and truly loved being around each other. I was a bit confused because prior to that she would tell me that she is not ready for a full commitment. While gone she would e-mail and call daily, saying how much she missed me, she just wanted to hear my voice, and that we are going to spend so much time together, and that she can't wait to spend the rest of our lives together. That went on until about 3 weeks before I got*back. Her brother visited her and they would always go out and party, I went from 4 e-mails a day to 1 every 3 days and no calls. When I got home I saw her and she hugged me for a long time saying how much she missed. For the next couple of days I admit I was not acting myself, I had jet lag and recently had a death in the family. I was rude and distant towards her, she was hugging me and very friendly. She went out w/her friends and told me she would call that night, she didn't. I saw her the next morning and I barely recognized her, she was so hungover. She told me she did not want me around and we would talk later. I went over later and saw another guy there, I apologized for my behavior and gave her a necklace, which brought a tear to her eye, she then said she just needed space. All this took place in the hallway. About a week went by and we talked, she once again said she does not want a commitment and that the way I acted when I got back made her re-think everything. When I asked about the guy she said there are a couple of guys she has been hanging around who are just friends, she started hanging around them about the same time she stopped with the e-mails. I told her that I loved her which again brought a tear to her and I asked her what she wanted. She wants to hang out and talk every now and then. Then she started talking about marriage again!! When she left we were joking and laughing like we used to. I don't know what to do. She was never a big partier but now she is, I asked why she never did with me and she said that I am different. We had something really nice going until 4 weeks ago. Am I getting played here?? Should I just let her go?? I need some help.
