Broken

I am brand new to the realisation that my husband is a porn addict. I didn't even realise this was an addiction. I first found out he used porn about 13 years ago. He said it would stop. Over the years there have been at least two more confrontations, I guess haven't taken it seriously enough to look into it properly until last night. I confronted my husband, stated that this has been going on for at least the 14 years we've been together & he didn't even deny it, didn't say he was sorry, just that he didn't know what to say. Rightly or wrongly I have told him he needs to go and see someone, this is his very last chance or our marriage is over. We have two children (13&10), I have banned him from our bed, preferably I would like him to move out! Which means our children and the hole community will know we're having problems...not something I really want to happen! I suffer from depression/anxiety, my husband has never really understood/supported me and I feel we have no emotional connection. Where do I go from here??? I need help!!
