That's why I used to refer to my exes family as the outlaws instead of inlaws.

I'll never forget the day that I walked right over to an adult neice and sister in law, them not realizing I was approaching, to hear just exactly what she thought of me.

I used to complain of migraines when I first started attending family functions. Then I found the source of distress.

That day I walked in on that conversation, on a wedding anniversary, where their kids bdays took precedence over adult events, well I paid dearly for that, that evening. I digress.

Point is, they don't sound worth bothering with. Maybe your husband can go by himself and let you know if they are alienating him or both of you, next event. Bow out, feeling under the weather.

Find others to be around. Maybe set up cutomized fb privacy, where not a clear delete nor sharing of yourself. Deleting friends is complicated. Customization, now that's something empowering...
