He left his fb page up, in fact mine was up at the same time and they merged....so I could see my profile picture and wall but his name on the right and his messages, was weird. So in his messages, which I thought were mine until I clicked, were 10 exchanges from him and an old school friend. Lots of smilies, ggl (not lol which was cringeworthy enough) and little mention of me.
Now I wouldn't put cheating passed anyone, let alone my DH...rumours have not exactly never mentioned him, even on the internet. We have had many an issue in our relationship, but cheating would be the end if I ever found out for sure. I'm not sure I'd be heartbroken, just wouldn't ever forget.
So AIBU to sit him down and have a talk about the route to cheating and how one minute your marriage is dull, you catch up with an old friend, you reminisce and then hey presto you're having to decide whether or not you'll kiss.....
