OP here with an update.
The reason I decided to send OM a response of leave me alone because the last conversation via facebook we had had me leaving the last message (a year ago) as that we would part as friends, it was his further actions after that caused me to do a cut direct. Then we didn't speak for a year. Then when we shared a table for B's birthday party it was after that he tried to reestablish contact. So I sent that message off, and blocked him. I did go to 80's night last Sunday, and OM was there. He tried to pull I just want to bury the hatchet again, to which I replied I'm not interested, leave me alone. And he did for the rest of the night.
I did explain to B what was going on, and that if OM was sitting with him at a table I would not be able to as I am not speaking to OM, and he said he understood and since he's known OM longer, he thinks Om has issues with dealing with people and social situations, so as others had thought it probably is a pattern for him.
Then I log into facebook today to find a message from his other account (which is now on the blocked list) which got no response from me as I have said all I will say to OM, but shows that he hasn't changed. - "Let us fast forward to 2013. I am not interested in dating
or hanging with you. I am interested in having a pleasant time at the club. I am interested in hanging out and associating with my friends such as B and V. I have known them for several years. When you decided to become friends with them while I am also interacting with them, I had decided to make peace, so we could all tolerate each other. I thought that it was the right thing to do. Sitting at the same table together and being adversaries was not working out. I thought that I was taking a positive step by proposing a truce, but my efforts backfired. I am kind of hurt by all of this drama. I have recently talked to both B and V about this rift that you and I have. You have won the battle. I have decided to take a hiatus from Billy’s and not go there when there is entertainment that we both prefer. I am relinquishing my right to be there. I am giving up my friends. I am giving up my music. You won't have to worry about avoiding contact with me. I'll simply go away. You win!"
All of this was in response to the message I sent him - Look, I do not want to talk to you or be friends with you. I can't stop you coming to the bar, and I don't intend to harass you in any way. But I do NOT want to have any sort of relationship
with you. I have made this clear to you before. Leave me alone. And then me telling him to leave me alone the next time I saw him.
I suspect OM will stop coming for a bit to the bar, he lives an hour away from my city, so I won't have to worry about running into him again for awhile. If he tries to create other accounts to message me they will be blocked with no response, and if he does show up again and tries to make peace he'll get broken record Reader
, stuck on leave me alone if I can't walk away at the moment which will be my first response should OM do so.
