My girlfriend of 3 years broke up with me. I'm devastated. What do I do?
So my ex who I have know for 8 years since we were in high school, we are now 21, broke up with me after 3 years. We grew up together throughout high school and she had admitted to me that she was always in love with me. I had always been there for her through her difficult relationship with a guy that had emotionally broken her. We were really close friends and got closer as we got older. As our senior year came we spent a lot of time together and had finally kissed. After graduation I had asked her out and it was amazing. The beginning was perfect and life was perfect. We spent everyday with each other and did everything together. After our first year, we still spent everyday together and still did everything together. We were each others best friends. We talked multiple times everyday for hours on end and would tell each other how we loved each other. We would make plans of our future and how we would live together and get married and have kids. We were in love and our families knew it. They thought we would get married one day. Her family loved me and my family loved her.
Our relationship never got old because we always did something new, even though we did have some routine things. I had bought her a promise ring for christmas, which she still wears today on occasions. I promised to love her always and she told me that she would always love me. In may of '09 she turned 21 and we had celebrated with friends and family, though I was still 20 at the time. She has never been a very social person and has been shy around new people that she does not know. She was never a partier or a heavy drinker. But in July she had gone to san diego with a co worker and friends for 4th of July weekend and had gone to clubs and bars. When she came back I had noticed that she was different. Apparently she had fallen in love with going out and clubbing and drinking and meeting new people. That was all that she wanted to do now. Since then, she would go out every weekend with co workers and friends to clubs and bars and not get hoe until 4 or 5 in the morning. She was going out with her co workers more than she was with me. Months later she had gone to her ex's house for a party for his 21st birthday. I was completely against it but she went anyway and there she had met up with an old high school friend. They kept in touch and talked everyday afterwards. They became very close as she had helped him put together his grandfathers vigil.
A month later, she broke up with me and said that she was confused about herself and needed time to figure herself out and wasn't sure how long it would be. I was devastated and begged her not to do it but then finally agreed. I went on NC for awhile but then I couldn't take it anymore and I had texted her. A few days later we had breakfast and talked about things. She said she was happy experiencing new things and loves to go out. She explained that she still loves me and cares about me but now she had developed feelings for this guy and cares about him. She said that they see each other a lot and talk every day. I took her home and we talked more. She still wasn't sure how long it would be because she was still figuring herself out. We had kissed passionately and she said that she missed me but cried and said that she was sorry because doing this was too hard and was only making things worse. Every now and then she texts me saying hi and how am I. I try not to respond but sometimes it is too hard and I end up saying hello back. I know this is bad because I feel like I want to talk to her all day and night everyday.
I am still so deeply in love with her even though she has broken my heart. I know she is the one for me. I just cannot take her being with someone else and it is difficult seeing how different she is. She is the same person I fell in love with. I don't want to be with anyone else, I just love her too much. I can't let her go. I'm afraid to lose her forever. What do I do?
