Think DH is cheating with one of my closest friends. Not 100% but I've had a gut feeling about some stuff for a while now. Just little things that made me feel uncomfortable. Fast forward a few months and he's left me. There was a bit more suspicion about there being someone else but he of course denied it. Anyway a couple more things have happened to make me suspect this friend and I just don't know what to do! On the one hand she has been amazingly supportive and encouraging me to look at the worst of him and the positives of him leaving. She is very unhappy in her own marriage but it is not straightforward for her to leave so I wonder if they are having to wait it out and he has left first to make it easier for them to carry on. I have found the breakup hard because although things weren't great we have been together for 35 years. Obviously them getting together would rock our circle (we live in a small village). I hate thinking like this of my friend as she has been amazing but I can't ignore my gut and there has been a couple of other more recent things that have happened to make me even more suspicious. Do I confront and risk losing a good friend if I'm wrong? Do I wait it out until I have proof? Is it wrong to keep quiet and lay the groundwork to find out the truth? Shes always seemed such a loyal person it makes me feel sick to the stomach that if my suspicions are correct she has betrayed me in this way (I'm not putting all the blame on her by the way but DH has left me so his betrayal of our life and marriage is not in doubt). I'm even beginning to wonder if shes just being a good friend to keep the cover. Sorry for the ramble but what do I do? How do I figure this out without it all blowing up in my face?
