Also a situation coming up is a 21st party for my s21 fiance (her 21st). It will be held on a property, quite a distance from home and requires an escort to the property, so we don't get lost. This party will be an overnighter where we bring our own tents. Anyway I found out that W will now be coming (originally wasn't) and is bringing OW with her. So my question is how do I deal with this?
If it were me I would go for my kid, but I'd make sure not to pitch my tent next to W's, LOL! I think she and OW are going to feel mighty uncomfortable with you around, but that's their problem, not yours.
