Rainyday 107 makes a good point in terms of his behavior being illogical. He seems as though he's all for working for your forgiveness yet he continues to be out till all hours of the morning. Given that you have decided to see counsellors both together and separately in the past, it's clear that there is some form of amicable-ness to your relationship still (especially given the kids), and so if you do decide to split permanently (and I personally would given the situation), there are services available for you. Personally, I have used a mediator and online service for my divorce. It sounds strange but if you're able to communicate well and be civil, it can save a lot of heartbreak and money. The service I used was called DivorceGuru. PM me if you have any questions, but I sincerely wish you the best through this difficult time!
