My girlfriend and I dated for 6 months now.. We've hit 3rd base.. done a lot of stuff together and we were really close. She writes me love letters usually.. and she's given me around 20 of em now.. Just yesterday she said she wrote me another one and asked me to go to a place to collect it. I thought it was another sweet letter that would make me lovestruck. But it was about a breakup. She said she lost interest in me. She even mentions that Im was never a problem in the relationship and its just that she doesn't wanna continue this anymore. Even according to me things were extremely smooth, and no problems/fights were there. She lost interest in me, ended the relationship, but still wants to be friends. She wants to have memories with me as a friend hereafter.. I don't know what to do guys.. help?
