My cousin is throwing a huge 10 year anniversary party this July. I don't understand why as she's never been happy with her dh and during lockdown he lied to her, took money stealthily (they struggle financially so it's not like it's something he could afford) and spent it on Class A drugs, has lied in the past, as some examples. I've tried to broach the subject with her but her immediate reaction is anger. So I've dropped it now.
Aibu to think there's no logic to her thinking? Why flaunt something she is unhappy in? Why make it into a massive party? I don't understand? Aibu in my thinking?
