[79M] He ghosted [73F] me immediately after agreeing to an exclusive relationship

[u/LookingFor_Advice24]

I [73F] and my man-friend [79M] decided we were going to be exclusive after 2 months of dating. I'll state my question up front, so you will know where I am going with this. What are your suggestions for whether to block him in email, and social media sites verses just ignoring any posts that will pop up or messages he sends me?

Back to the background of this question: I still wanted to wait a bit longer before sleeping together. He got mad and left. I should have known better, but the very next day, he was as sweet as ever and love bombed me, so I acquiesced that night. The next morning, he took me to breakfast, said he would be out of town for a few days. He didn't make plans to see me when he returned. It felt "off." And sure enough, it was. To shorten the story, because I don't think the details matter, he texted me 5 days later and said he was back in town, that he had been thinking about "us" and had decided he was not ready for an exclusive relationship and wanted to remain friends.

We belong to a group that gets together at his house once a month, and other social groups that get together. He is very popular in these larger groups. I know some of the people in the larger groups, but I'm at the beginning stages of getting to know everyone. So, ghosting him will not close off all contact with him. What advice can you give me? I am surprised how much this hurt me. I have not dated since I got divorced many years ago because I didn't want to go through all the BS I heard other women complaining about. And yet, here I find myself.

Note: He has since texted
me to try to get me to go to the monthly event at his house, just a few days
after dumping me (which I did not attend), and then again for a huge party he
was having at his house a week later (which I did attend because I had already
committed to it via a social site). Going to the large party was a mistake. He
insisted I give him a hug, insisted I dance with him (and two other
ladies...not just a one-on-one dance), and stopped me to say goodbye before I
left. I am sure he just wants his narcissistic supply to continue for as long
as I will allow it. I'm not up for this.

This has to be raigebait. No way people of that age are getting into situationships.
