One anxious attacher to another-- what are you doing to get that under control? Because this post describes a LOT of communication attempts that im not sure were helpful or productive to you.

Ghosting sucks, but unfortunately there is nothing you can do to force someone not to ghost you. I think your effort will be better spent actually working on moving to a secure attachment style so that you can learn to manage your own anxiety when it comes to interacting with other people. You will probably get ghosted again someday, and hopefully you can get to a place where you're not obsessing about trying to make final contact.

I'm also going to challenge the assertion that you had a relationship here. Your first post doesnt say whether you had a DTR talk with him, just that you were dating for 2 months, seeing each other once per week. I'm not trying to minimize your feelings for this guy, but it sounds like you thought this was more, and I wonder if he was on the same page. I can't tell if you were idealized, but thats a common behavior for anxious attachers and something you want to watch out for, because it can feed the attachment. But beyond that, in the future, you may benefit from being more clear about your expectations, goals, and eventually, how youre feeling about the relationship, to ensure you and your date are on the same page.
