Poorly as it is, love is an irrational feeling. My ex gf cheated on me and treated me like shit in the last days of our relationship and i couldn't handle it. The thing is i know who i am and i know who she dumped me for and that is also not quite understandable. (Seems a little bit arrogant but it's my opinioin) I tried many things to get over it but for 8 months i think about her everyday. It's totaly fucked up. All your advices are good but they are not different from any other girly magazine on this world. I'm still not over it fully but when I reach the point where i am i will write my experiences and feeling into my blog and share them with you.
