Hi, I am hoping to be able to use this as a safe sounding board - my mind is a big, confused mess and I need a bit of perspective from people not involved 
My Husband and I have been married for 9 years, together 12. We have a 15 yo boy (from my previous marriage) and a 7yo girl. We live in a house tied to his job and far away from any family. Thing is, I feel that maybe I should leave.
Not just on a whim - there have been issues! During our time together he has unfortunately managed to gamble massive amounts of money away. The first time to the tune of £35k (before we got married - don't ask why I went through with it as I don't know the answer
. The second time towards the back end of last year; this time £28k. He is now bankrupt.
We unfortunately also lost our family home due to Hubby renting it out to his best friend (we were working in a different part of the country) who then sublet it to several people, took their money and then never passed the money on to us. As we couldn't afford the rent on the house we were in and the mortgage on the other, we lost that house
. This other person had been the best man at our wedding and the killer is that they are still friends now. 
Fast track to now and I have supported him with his bankruptcy application and taken care of the finances. We could continue as we are - he is not physically abusive or particularly nasty in anyway. However, I feel absolutely nothing. No, that's not completely true. I feel contempt, I feel deceived, I feel monumentally stupid for not seeing this coming again, I feel drained for living on such a shoe string budget for so many years and having nothing to show for it.
My son is fully supportive of a motion to leave - he's never been the biggest fan. My daughter is blissfully unaware that anything is going on.
Am I being selfish or dramatic in wanting to leave?
When he touches my skin recoils away from him. Perhaps this is normal and I will feel better towards him in the future? Would you stay for the kids? Is it better for the kids to stay together?
Arghh - I have no clear thoughts anymore and feel like a shell of my former self.
Please reply with some words of wisdom - or humour. I'd take either!!
