I found an email on DH's phone earlier to a work colleague who is currently off sick. It said I miss you followed by 3 kisses. He has form for this kind of thing. I'm not sure he has ever cheated on me but I've found similar, flirty messages before. He did once kiss a girl whilst out with his mates but got cold feet and came home.
I think, for me, the marriage is over. I don't think I trust him but my heart is breaking for our 2 DC's.
Am I over reacting or would this behaviour make you call it a day too?
