Typical, there's me yesterday posting about feckless exes and how to ignore, avoid etc and one of mine pops up!
He wasn't a long-term relationship, just someone I went out with for a couple of months, although we saw quite a lot of each other, about four times a week, and he talked about me meeting his DCs so acted quite serious. At the beginning he was very loving, attentive, all the usual tricks they play.
I started going off him a bit when he mentioned some weird stories about revenge at work (can't go into too much detail just on the complete off-chance he reads Mumsnet, because it would totally out me!) and when he kept self congratulating himself about how many women he'd slept with, how good looking he is (erm he's alright, although had his day really with a pot belly, don't want to be nasty but just saying smugness is perhaps somewhat unjustified) and how he'd cheated on his ex wife loads of times, although he was a good guy because he was always back in the marital home by ten o'clock 
. Because he had started showing signs of being a bit unstable/abusive etc I decided to back off gently and said that I was a bit busier at work these days but we could stay friends. That seemed to work and we exchanged a few matey casual texts and that was that.
Anyway, a couple of weeks ago he started sending texts again asking when he was going to see me. I really didn't want to see him again so made polite excuses saying that I was very stressed, which I genuinely am at the moment, busy etc.
This morning he asked me if I wanted to go over to his place, which would be completely inappropriate especially as he knows I have a new dp and am ttc and he has been telling me about all these women he's slept with! I made a polite excuse again, to which he responded with a volley of abuse. I put the firewall on to block his messages and just left SMS'es on from contacts but then someone from work sent me a message from a different number and asked if I'd got it so I thought I may as well turn it off as he surely wouldn't have bothered to send any more - when I went to turn it off I saw that 19 incoming messages had been blocked! God knows what he had been trying to say, luckily I didn't read them. Anyway an hour after turning it back on a message comes through (I'll translate and paraphrase now) that said something along the lines of "how is the low life and miserable cheap Moroccan slut? I'll spit on you until the day of judgement" I must admit it really shook me up. I know this man has a vengeful personality and I'm not sure how to deal with him. I hope he is not going to cause a lot of trouble for me, luckily he doesn't know where I live or anything and we don't really have mutual friends, only people in the pub we both met in.
I have NO idea why he's behaving like this, as I've only been nice and as I say he's well and truly an ex!
My gut instinct is saying ignore, although friends have suggested sending one final message. I have a feeling it wouldn't end there though and it'll just escalate. What do you think?
