Just last week I changed the privacy setting on Facebook, so only friends of friends could send me a friend request. This was to stop the requests I was receiving from fake profiles.
Yesterday, I added a new male friend, and he wrote a hello on my page. So today he contacts me to ask who so and so is because that person sent him a friend request. The person happens to be the exbf of my former friend with BPD, who I am friends with on Facebook, but not the BPD.
The exbf has never done this before with ANY of my friends, who quite often write on my page. If there was anyone he would befriend, I would think it would be a female

Timing is interesting in this as I have just started blocking the BPD's exbf from seeing my posts as I had a weird gut instinct the BPD was snooping. It was only a hunch, but a big one at that.
I've read where a number of people say that pwBPD are notorious for logging into their SO's accounts, so I find this rather "fishy".
Anyone else think this is odd timing?
