Nope not childish or bitter. Okay a little, lol. H knows that I would happily run over his GF, so no need to toss the friendship coin in the fountain in my case.
Keep your DBing up, get off of FB. I refuse to be friends with H don't want to know about his GF and escapades. He is not friends with our kids anymore, so he obviously doesn't want them to see his page. Very weird....
What do you want to do about camping gear? Did you buy it? Then say no. If you bought it as a "family" as you said, is it worth the emotion? I think not. You have better stuff to do than stress about some gear. Although, I did throw away all H's good socks a couple months ago lol! He left them so......
