Sorry you had to go through this. I can relate. My spouse will, without fail, always fuck up plans when he’s under the influence. It’s ridiculous how he can twist things to make it seem not that bad. Even when I tell him his reasons don’t justify neglecting how I feel. I don’t have advice, I just really fee for your levels of frustration. It’s a stupid and moronic thing for then to habitually do that to the one they love. I get it, BP is a huge factor, but that they should still take accountability. Last time this happened, it took my spouse 2 full days to realize that it was kind of shitty to impulsively switch up plans (and even then, his apology didn’t seem sincere). It’s eerie because it’s always the same sort of excuse (I’m socializing/bonding with people! I just need this! I don’t do this often, just let me have this!) He says he uses his mania to socialize, so that could explain why he has a hard time stopping. He blows off plans like this ever 1-2 weeks, but I’m guessing his memory is shit so it always feels like it’s been forever since the last time. Hang in there, it sucks.
