A couple of weeks ago DW and I were happy - a few problems in our relationship but loved each other, had fun together, have a lovely life with our child.
A week ago DW told me she'd been unhappy for ages, we have never resolved the issues we argue about and she didn't know what she wanted, and needed time to think. 2 days later she said we were separated.
This coincided with us having spent a lot of time with another couple, one half of which clearly has the hots for DW (we're all women). DW and this woman have (she told me) been confiding about their terrible marriages and had excluded me and the other wife from their activities. DW denied anything going on. I have now seen the proof that something is going on and it's obviously this which is swaying DW's thinking about our marriage.
What do I do? I want DW to come to her senses and realise what she is throwing away here, but I know what it's like when you've got the hots for someone new and can think of nothing else. I said I'd give DW space but she keeps insisting we are separated and she won't change her mind. The other woman also has 2 kids whose lives will be broken by this (as well as our kid's). It's all a mess and I don't think she's thought for a second of the long term consequences.
