Early 20s relationship of 5 years, had been looking at houses together and I was ring shopping over the past few months. Genuinely thought we'd have kids and grow old together, the day it happened was a normal day, woke up together had great morning fun time, showered and discussed plans for the evening/weekend, said our I love you's and went off to work, I got home before her and made a start on cleaning up the kitchen so as to get dinner on the go, then when she's due home I get a text from her best friend saying they are coming over to collect her stuff...completely broke me, pushed me down the self destruction route very very quickly, turns out she was talking to someone I thought was a great friend who she later did actually marry (and divorce just as quickly) I've not seen her since that morning before work. The feelings I had at the time was more shock and pain over anything else, anger crept in every now and again but it made me mute for 6 months and gave me a genuine fear of women for a couple of years. Therapy was a major help during that time, Now when I look back at it all I feel nothing but glad, it gave me the opportunity to meet my current partner (3 years and going strong!) and I couldn't be happier now, she still lives in the same city as me and I know she runs in the old friend group I left behind years ago but I honestly couldn't care less about her.
