I went thru the same a month back..we were in love for last 8 years while i was in nepal and my Bf was in china...I came here last year and found out that my BF was f***king chinese gals here..not just one but he was sleeping with endless....I felt yuk and disgusting..I left him right then...there is no forgiving a cheater, being in one relation u cannot go around fooling others at the same time...F* **her off...There are better people on earth. No crying for loosers....life goes on....forget those cheaters...He might want to forgive her, but ask him can he forget what has happened and what is the guarantee she will not do it again..It becomes a habbit and a disease later....Forget it pal
