how do you maintain LS friendships during a divorce without it being weird AF

were in the messy middle of separating. not divorced yet, living apart, custody being worked out. we have a really close group of LS friends weve known for years. some have reached out separately. some have invited me to things solo which is kind. but every time i show up its... weird. like they're trying so hard to act normal and i can feel them not asking the questions they want to ask. and i don't want to dump my divorce on them every dinner. how have ppl maintained these specific friendships during the transition without making everything heavy... vancouver btw
