Long story short, when i was 16 i had a boyfriend. His best mate (who we'll call Mark) develloped a crush on me. I was always very clear it was unreciprocated.
He seemed satisfied with that and was happy enough to be friends (though i would have called us acquaintances).
The boyfriend and i went our separate ways like teenaged love often does and this is going back 18 years now.
The thing is, Mark (the friend) is a drug addict. He's volitile, violent, been in and out of jail for various crimes, he's essentially homeless and that's just the short story (obviously, he's progressively gotten worse over the years. He was not this bad when we met).
Over the years I'd see him around sporadically, you know, in the city, hanging around shopping centres etc - he'd always chase me down to chat. I have always felt like the best approach is to be polite to him because he's so unpredictable (he's the type of guy that would pull a knife on you if you looked at him wrong).
So I'd humor him, say a quick hello how ya been and make up some excuse to leave.
Anyway, recently (probably the last 6 months) I've been seeing him more regularly and he's becoming harder to avoid. The last straw was running into him outside my kids school. Now it was a complete coincidence, he was meeting some shifty mate and it's quite a busy comercial/public transport area near by.
I hate that he now knows where my kids go to school, what they look like, the general area i live in, my routine.
I realise that I've probably bought this on myself by being nice to him but how the hell do i get him to leave me alone?!?!
I moved past all those types of people, im now happily married with children (obviously lol). My husband worries about my safety because of Mark.
I have blocked Mark on facebook as well as his family or anyone that might know him so none of them can try and add me.
I have never told Mark anything personal about myself (he didn't even know i had kids til he saw me).
I hope this makes sense, i didn't want to add anything that could identify me so it's possibly a little vague.
Any advice would be greatly appreciated.
Edited to add:
I absolutely never initiate conversation with him and i avoid places i know he hangs out. He's like a hawk, he can spot me out of a crowd and chases me down and sometimes just seems to appear out of nowhere.
I used to run into him maybe once a year if not longer which wasn't that bad, but recently it's been 4 or 5 times a month and more locally.
He is always high when i see him, his behaviour making that very apparent.
He's always as pleasant as he knows how to be with me but i know what he's capable of, truthfully speaking he scares the crap out of me.
