All I was trying to say is that most of the time we create the reality we imagine in our minds. It's like a self fulfilling prophecy. Even if people didn't like us initially, but we like ourselves, we can change their minds. I know it's easier said than done, because I suffer from this myself. I always assume things and stop there because it makes me depressed and it drains my energy to try, and thus I don't challenge my assumptions. But hopefully sharing this will be insightful or even helpful for you.

Right there, not knowing people's intentions is yet another sign of ASD. I think you have many characteristics of it. You don't have to seek therapy if you don't want, but be aware of that.

Making friends isn't easy. I'm trying it, but failing. I have a bit of shyness and anxiety and may be depression. All of these play in.

I'm not sure if it was mentioned somewhere: but do you have any friend at all other than your BF? I think if you have just one friend beside your BF it's good enough. I mean you don't have to surround yourself with many friends to feel connected, this is my view at least.

You don't have to trust people on your life from the outset. Make it superficial at the beginning. Like meeting somewhere in public every week. Gradually you can see what happens.

Have you tried meetup groups? I forgot if you mentioned this, too. Sorry if you did. But you can meet people in the meeting and that's it if you want. You can test the water in these meetings if you want to friend any one.
