I am stuck in the middle of something awful and would like some advice. Dp and I are friends with a couple who are currently going through real problems with their marriage and I am wondering whether to say something (and if so, what). The background is that the H is a friend of my dp from when they were at university - I have known him for years as he was out on the night we met. Ten years ago or so he met and married his wife and though we don't live that close to them we have been friends ever since - both of us have a couple of dcs under 7.
Now, he has confided in my H that he has met someone at work that he has developed feelings for. He helped dp and I when dp had a brief affair with a colleague a couple of years ago and saw the devastation that caused - I left him for a while and took the children and he helped sort of mediate in us getting back together.
Because he saw all that, our friend therefore hasn't done anything about his feelings as deep down he knows it is wrong, she'd probably turn out to be not half as great as his wife, and he loves his kids but they are really affecting things with his wife - he is following the usual script of getting worked up about the OW and his feelings and during this phase treating his wife like crap (been there, got the T-shirt on the receiving end of that one myself), then feeling guilty, pulling back from his feelings for OW and concentrating on his marriage and saying everything is 'fine' now to dp.
Now, this cycle has happened twice in the past year. The last time he was so awful to his wife that she said she'd leave him but he somehow managed to convince her things would be better and she stayed. The problem is that having been through all this myself I'm not sure I can stand by anymore without sticking my beak in. I admire the fact that he's trying really hard to do the right thing but I just don't think he knows how to, or how dangerous his half-arsed efforts at self control are?
I just feel that I really need to tell him that if he wants to avoid screwing up his life he should leave work and cut all contact with this woman because otherwise the process will just repeat and repeat until either a) his wife leaves b) he finds the excuse that gives him permission to test drive the OW and everything turns to crap. I know it's their business and so far I have kept out but dp is useless at giving him any constructive advice and I am dying to pick up the phone to spare a lovely couple the horrible pain I went through. Thoughts?
