Kids are very attached to W at this point. They will not go if mommy does not go.

As you build a stronger r with your children, that should change. For now, make it a "temporary" thing like "Mom has to work/doesn't feel well" and take them FUN places...often.
As for the GAL activities, they are not really about your kids. I mean they are for YOU as an individual mostly. If you need to build on the r's with your kids (and you said you do so I believe you) then do that.
But for some GAL you need to leave the house and be gone somewhere w does not know of
and
meet NEW people...not all men if possible.
I am not suggesting you date. But I think a little mystery can be a great thing.
