Basically this is quite a common situation I think - we've been married 12 years and have 3 young children, both work full time, not have sex much.
DH has developed a close friendship with someone at work that I feel has become totally inappropriate while he maintains they "haven't crossed any red lines".
I realise that the friendship is a symptom rather than a cause of our problems though - ultimately DH wants intimacy with someone and I don't want it with him.
I do love him though - we have a lovely family life together, he's a great parent and partner and I don't think either of us want to lose that but he feels rejected and I'm a bit bored.
I'm not sure where we go on from here though? When we initially had a big confrontation about the friendship and our marriage I kind of resolved to try harder at the romantic/sexual side of things, date nights and more sex. But actually I don't really want that 
Is it possible to maintain the partnership and parenting side of our relationship but separate from the romantic/sexual element? I'm not sure if it's open marriage I'm thinking of exactly but in lots of ways we are really good housemates who are raising happy children together so if he/we want to find intimacy somewhere else then could that work?
I'd particularly love to hear from anyone who has managed to separate from a romantic relationship but continue as a family?
