it's not so much the fact that no-one's thumped him. Or read him the riot act. It's the apparent lack of reaction, full stop.
I understand why someone who finds herself in your position would be 'numb' Ophelia, I just don't quite understand why everyone else in your real life is also 'numb'.
We are all normal people on here and look at how outraged the responses are. Disgusted, fuming, some people getting upset over it etc. etc. Normal human reactions.
But in 'real life' the reaction of everyone is muted to say the least.
So has no-one said 'what a fucking bastard' or worse, or got angry on your behalf? If you were my friend I'd be apoplectic, and if I saw him in the pub or the street, I'd leave him in no doubt whatsoever as to my feelings. Not just report - oh I've seen your husband of 12 years who was still living with you a fortnight ago, walking down the street, bold as brass, with his new girlfriend and her child.
Where are the people who are disgusted, angry, outraged in real life? Any right minded person would be and perfectly natural and understandable.
Also, hope you don't mind me asking but is it a very small town/village as lots of people seem to be running into each other and seeing each other - like you seeing him going into the restaurant and kissing in the street?
My ex moved to the same town as me after we split - but I've never so much as clapped eyes on him once in over 10 years. Lucky I guess.
