I know it hurts Realgonekid and i can feel your pain on this one. That inevitable moment when you see them with another man rips into your heart and you experience true hurt and agony at that moment,i know it did with me. But remember this,they are all actors/actresses to an extent (hell my ex was even involved in a local theatre company, the strange thing is i always found her a little wooden when she was on stage,where as in her real life "acting" she was oscarworthy

. When you see her she is not happy,she truly isnt,she is putting on a performance.The same performance that possibly snared you in the first place. The new man falls for it just as you did,its only over time that he will begin to see through it all and realise she is not as genuine as she appears (i realised it fairly early into the realtionship,but chose to ignore it,silly silly me )
She moved into my house and stayed for about 9 months saying she wanted to start a family with me and at first everything was so amazing.
There where a few red flags which I put down to her being a little quirky and decided that they where part of her charming, slightly crazy, personalityI think i can say quite a few have us have experienced a similar scenario her. We almost fall head over heals for that quirky side,it makes us feel alive (watch the film "the garden state",looking back it reminds me a hell of a lot of how and why i fell for my ex.The starting a family thing was quite strange in my case. The first night we got together i went back to her flat before we had even talked of the possibilty of a relationship. She was in a two bedroom property at that point. Her flatmate recently having moved out meant she was on her own there. She took me into the empty second bedroom ,telling me she wanted to turn it into a nursery for the baby (what the hell was i thinking that night?i had just gone to a girls flat not expecting anything,and there she was
talking about us having a baby together.RED FLAG ALERT
Its a cliche ,but time and distance is a healer. In the end as much as we tried,we couldnt save them,and eventually they end up digging themselves deeper and deeper until they either reach rock bottom and start trying to get better,or they continue down this miserable path,forever bemoaning there lives. Just remember. You did not fail,you did all you could for her,and over time you will find peace with that. Keep on keeping on
