I've been married to my husband for 15 years. We have 2 young children, aged 11 and 6. I haven't been happy for many years and we don't really have a marriage. We just share a house and the children. We are financially co-dependant which makes things difficult. I feel very guilty about asking for a separation because I feel im punishing him for something that isn't his fault and he feels very bitter (understandably) which has made his behaviour towards me over recent months quite difficult to deal with. Our eldest child is sitting her Sats next month and we had agreed to not say anything until after that as she's already quite stressed. At this point I'm looking for advice. My husband is pretending this isn't happening. I know he won't take any steps to move things along and I need to know where to start as I haven't a clue. I don't have anyone I can talk to with experience of this situation so was hoping someone here could help?
