i’m inclined to agree. you can’t expect someone to blank a person because you don’t talk to them: plus this seems a relatively short friendship if it’s only been since april. it sounds op like you’re already a little annoyed by her and the support you’ve offered to her when she’s been going through hard times - it’s a friendship of five months, if you’re already thinking that you’re done with her then walk away.
i posted at the start of the year here about my toxic friend (i’d forgotten but just saw the post!) - and we haven’t spoken for the whole of 2022 so far
she has main character syndrome in the extreme and cannot retain details about anyone who isn’t her. i lost two grandparents in 2021 and she straight up forgot that my grandmother had died. this is a friend of over 20 years. she likes people who agree with her and will sit and nod while she talks about herself, i gave some blunt advice about her relationship and (as she left my house) knew that she wouldn’t talk to me after it because that’s what she’s done with a stream of other friends. and… she hasn’t
i’m truly not bothered as our friendship had changed deeply over the past few years and i think we were both going through the motions of what it was when we were younger. she’s a perfectionist in that she expects everyone around her to behave perfectly towards her because she’ll cut them off for one misdemeanour or careless comment and i don’t need that stress. i have lots of other lovely friends. i do think she’s going to end up rather sad and lonely though.
