Hi,
You have articulated yourself really well.
No one can understand the pain and torment of a forced marriage (unless) they have been through it
themselves. I certainly can't imagine your situation as have never been married, yet losing someone you love and care for is a very traumatic event and takes time to heal from such an experience.
Not everyone who has suffered from childhood abuse have been very severely damaged by it. Your wife may have suffered from a variety of emotional and/or mental health problems as a direct result of her abuse as a child, and did not want to get the help and support she deserved? - a vast amount of childhood abuse survivors will likely get the therapy they need; yet the affect of such a traumatic experience can have lasting damage for many, but not all.
Perhaps she also felt under pressure from herself to get married? - some people want to get on with their lives and forget about their pasts, yet does not work out all of the time for everyone. The important thing here, is that blame causes bitter hostility if you reflect too much about what has happened between you, so learning to accept that you were both on different life journeys, instead of holding onto blames and regrets will help you deal with the loss far better? - your wife's past may have only contributed a small degree to the separation, there could have been other reasons that she did not fulfill your expectations of her, yet we are complex human beings with complex needs.
Your courage to move on and forgive her mistakes will strengthen your faith in being able to find other suitable women, holding onto something that didn't work might only make you feel less able to get over the loss.
