BPD ex keeps contacting me from time to time + feeling insecure.

[Family Court Strategies: When Your Partner Has BPD OR NPD Traits.]

Hello.
I was in a relationship with a guy suffering from BPD for 2 months ( He said he saw me 7 months before aka the relationship has strated in his head at that time)
I knew he had BPD after deciding to breakup ( I was so tired emotionally).
I didn't contact him at all after breaking up ( The breakup was with no direct contact ... I just left and told his friend so that he won't be alone).
Right after he knew i broke up with him , he came to my house because i wouldn't answer the phone ( Living with my parents ).
I saw him 2  times with friends but we didn't talk or even say hi.
Sometimes he calls in the middle of the night and i never respond. I blocked him everywhere in social media.
The problem is that i feel a little bit insecure about myself. Everytime the door rings , i say it is him. How can i get over that feeling ?
Thank you.

hi Christine15 and

to give us a clearer impression, can you tell us a bit more about what/why led you to break up with him, and how long it has been since the breakup?

Hi Christine15,

Can you tell us a little bit more about the BPD behaviours? To answer your question it sounds like maybe you didn't get closure or grieve the r/s do you still have feelings for him?
