Interesting this question. I just want to remind what was so helpful for me when I discovered the site. First, I was amazed by people welcoming me, syaing you aren't alone. And special words relieved me, it was the first time in months I could be relieved ( for a few minutes). It was: "day after day, step by step". I dicovered I could be relieved by very tiny things. I read read and reread many times the phrase " Believe nothing he says, half what he does". A wonderful thing was " Dont talk to family and relatives, they wont understand". I rushed after work on the site only to "be" with persons like me , saying " you aren't crazy".
It was very further when I was able to read about " detachment", but with time, even while thinking to him every minut, I could feel in love and detached, I mean in peace inside, believing my love was a warm stuff inside me, and nobody could take it to me. I read and reread about OW: "she is a bandaid", "let their titanic sink itself".
Oh , 21 months after BD, I have progressed, and so graceful. Hugs, Hope (with my approximative english, sorry)
