I think you are doing the right thing. Similar situation for me - but he left then told me re OW. I know my husband very well and the guilt got to him. He fell in love (well that's what he thinks) with someone else and made the hard decision to end our marriage to be with her - because he believes the love is gone between us. That was just on 3 months ago. I'm still on a coaster - I keep waiting for his fling to end and for him to realise that there really is love left between us. I am in a sense dropped the rope, but I still can't let go 100%.
