Speaking as someone who had a horrifcally cruel first marraige I have to admit ( and it isn;t easy to do that) that I did get the marriage I and everyone else expected and while I did not perhaps deserve what I went through I could have left and I could have done things to prevent it.
I started dating him while he was seeing someone else and knew that he had made her life a misery because he weas chasing me, i therefore should not have been surprised when he did the same to me.
I stopped with him and eventually married him despite having very little in common with him and even disliking much about him - because I placed designer handbags and flash holidays over a loving relationship.
I allowed him to treat me with a complete lack of respect because I had a lover and lots of friends that made up for his behaviour. I selfishly and rather stupidly thought I had a perefect life a man to pay my bills, a man I loved and a great social life. Falling pregnant though meant I had to give up the other man and I had less time for my friends so the emptiness and cruelty that went on within my marriage became glaringly obvious and impossible to love with. But i had allowed that situation to develop and had chosen to marry him so I cannot absolve myself of all blame and responsibility.
I managed to mantain the relationship by telling myself that he would change - only an idiot marries someone hoping he would change - and I was that idiot.
