I am indeed very sorry to hear the turn of events in your life. Financial separation certainly seems to be the way forward for you.
I realise how great the betrayal is that you feel but please bear in mind that your wife did not ask for, nor did she want her addiction – she will not have deliberately hurt you or her child however much her behaviour suggests otherwise. It is a terrible addiction that she owns.
It is good that you appreciate how good your wife is with your daughter – I hope in time your daughter will learn about the addiction that hurts her mother and that she can be helped to understand. I appreciate your anger at the moment and the feeling that you do not want to see your wife again but your daughter is not old enough to make such a choice and in my opinion deserves the right to make up her own mind when she is old enough.
I wish you, your daughter and your wife well James – I know you are making uncomfortable decisions and that the outcome of your relationship is not the one that you wanted. Unfortunately the addiction to gamble is very strong and proves too much for some. I know that however much you love someone, sometimes loving them is not enough.
I hope we hear from you again and that you all pull through this terrible time. Your wife is to be pitied not blamed but I know this takes time.
