Married 12 years. Husband been sending flirty texts and emails to various women but never been away from home to spend night. Husband non engaging and non intimate with me for past 3 years. Husband cannot accept that this is unacceptable behaviour so I'm done with him. I've told him that. However when we broached topic to children (12 and 10) they were completely and utterly devastated. So much so that I worry my son would do something to harm himself. They beg us every day to be friends and we put on an act in front of them. My friends and family say I need to divorce him now but I want to wait and start getting the children used to the idea that we tried but couldn't fix it. He has also told them if we split then they should blame me. He would try and turn them against me so I'm looking at the 2 year separation on the basis that we've not been a couple for the past 2 years I.e no fault divorce and just gradually educate them that we've grown apart. Anyone help please xxx
