My wife died 18 mnths [...].
My wife died 18 mnths ago & Ive a new girlf who moved in with me recntly. My friends wives are being standoffish with her & I don't know what to do.
You have to move on with your life and it's good to see that you have after the tragedy of your wife's death.
If your mates' wives can't see that you deserve to be happy, just don't bother with them. You can still see your friends on your own at the pub or the football, but you don't owe these women an explanation.
If they're not grown-up enough to give your girlfriend a chance, then they're not worth knowing. I'm sure your wife would have wanted you to be happy.
