hey introvert, and welcome to bpdfamily.
im an introvert too! youre in good company!
but seriously, youre in very good company. many members here can sympathize and empathize with exactly what youve been through. i understand youve read some things, but these relationships vary probably as much as any other; my experience was similar to yours. my ex was a fantastic gift giver and a bit of a care taker. and i mean, one of the best give givers ive ever met.
it may be useful for you to know, that taking a break may be, as youve seen, perceived as abandonment by a pwBPD. that doesnt mean you intended it, or that it meets reality. my intentions were frequently not my uBPDexes reality. cheating is extremely tough stuff, and im sorry you went through that

https://bpdfamily.com/message_board/index.php?board=45.0as for the subject of your post, and disposing of the relationship memorabilia: i didnt. i kept every bit of it except stuff like toiletries and clothes, stuff that didnt need to be kept and wasnt part of the relationship. all the letters, conversations, and memories, i kept, but i put them away. this is a very personal decision. some feel that it is best for them to dispose of it all; i, and others, did not. to me, theres no point in dismissing our exes compassion, gifts, or the fact that they were very good gift givers. these relationships werent black and white; they werent all good or all bad.
