Hi all!
It’s been almost 2 months since the last contact with my ex. I’ve been working on my beliefs in regards to myself (more on that later) and general mindfulness. It’s been a process, but I am motivated and open to suggestions

!
There is one particular aspect that I am having trouble with.
Our last (video) conversation was (from my point of view) friendly and pleasant. I even felt excited to share that I enjoyed these drinks that are only available where he lives, and he said he’d be happy to send them to me. I ended the call because it was supper time for me, although it did seem like he wanted to talk more. I said it was lovely to talk to him, and that I am happy.
After that, silence. We used to exchange messages here and there, often initiated by him, but after this call nothing. I sent him a text a couple of weeks later to ask for a recipe, and it seemed like it wasn’t delivered (which would happen whenever he blocked me). I haven’t tried to contact him since.
Why is this bothering me so much? My brain is overthinking this interaction and keeps coming back to it. I circle through:
Was I too friendly? Not friendly enough? Is he too busy with his girlfriend? Does she not want him to be in contact with me? Did he feel like I wasn't worth having in his life anymore? Why did he change his mind so suddenly? Did I just think that I was confident but really come off as disingenuine?
My mind knows a good way to deal with this sort of thing is to allow the thoughts to be. Fighting them just makes it worse. Plus, I know that I am doing the right thing by not reacting (I mean not trying to contact him) and reinforcing feelings of calm and confidence in the knowing that this ultimately
doesn’t have anything to do with me. It's unfortunate, since I had felt confident in myself during that conversation, and happy for him and open to being friends, but now I find myself having these old thought patterns where I blame myself.
All of that is great and all, but for today, I just want to know what you guys think and if you have any advice on how to let go.
