Boyfriend problems

[u/Scary_Anywhere2530]

i started talking to this guy a month ago, and we have talked about making things official and meeting each others kid for a couple times. i finally told him that i suffer from BPD and that im in therapy for it. and we had a really mature conversation about it but he mentioned to me that after we are done hanging out i get really quiet and it makes him feel like he did something. but one time its because i just woke up and the other is because i was on an emotional high and came crashing down all of a sudden. so i guess my question is how do i go about becoming a better partner for him and for me?
