Since being separated from stbx, for some reason a friends dh seems to think its his responsible to keep an eye on me, at first I didn't think too much of it, would pop in every now and then, message to see how things were. Then he was messaging every day, then making up excuse to come to my house for this, that or the other. Then went to messaging every morning to say have a good day, during the day and last thing at night.
I have found out that he has been stalking me on whatsapp and messenger, ie I was online and he messaged me and I didn't read or reply to his message. He had gone through his list of mutual friends, found a number of a divorced dad we both know, then he gave me the third degree about him, and what a awful shit he is etc. I wasn't even talking to him, but friends dh claims we were going on and offline at the same times...so he was clearly watching my status. Same on fb messenger, I was on there and he sends a message saying, see you are online 
.
After a recent party he and wife had argument. She doesn't like fact that he chats 'so many woman'. I don't blame her and have said so. I got a blow for blow account of their fight, including him telling me that his dw had chucked him out the house. I know that he was waiting for me to say, oh come around here, ill put you up. Except I didn't. He kept messaging saying was hungry, had no food, sleeping in car etc as dw chucked him out. I replied 'sorry' and left it at that. Next day all is sorted out and it appears he went home that night, clearly didn't get his way to come here, so made up with dw and all is sorted.
So I told him, we cannot chat anymore, not fair on wife (I thought she knew we talked from time and time as dw and I are friends too).
Now the messages coming through are just pure pathetic. 'you are my only friend', 'I NEED you' what he needs me for, fuck knows (to which I did reply that need and want are two different things.) Anyway, I just can't do it anymore and now have blocked him as its just getting so ridiculous.
So why do I feel so crappy about it???? I know I am a sucker for saying no to people as I am a big softy, but I hate being put in this position. Stalked, creeped out, got placed in the middle of a fight between him and dw.... but still, yet I feel shitty about it.
What's wrong with me?? FGS for the first time in 20 years I have some space (separated) and now I get lumbered with someone else's husbands shit.
Oh and on his whatsapp profile pic today is a sad emoji face as I haven't replied or read his messages to me WTAF!
