Advice for attracting intimacy into one's life?

[Tae]

Being interested in someone doesn't always work. I was really interested in someone, and they ended up blocking me on Facebook.
Another person blocked me because I complimented them and gave them some advice about their writing.
So I've been blocked twice in social media for being too friendly.

I suspect there's more to the story, on both sides. This is distortion at play. For example, "complimented" might mean you called them beautiful, which to you was perceived as a compliment and to them was perceived as sexual harassment due to how they've been treated in the past. While giving advice on their writing may have been intended positively, unsolicited critique is an enormous trigger for some people.

You have to engage with people on easy mode first. Which sucks when you're a deep mode person. I find it works best to seek consent first for anything that could be in any way upsetting to someone I'm not highly familiar with already. For example, recently a friend of mine who I've known for a couple of years has been working on a story. I have witnessed a reading of the story and then considered it for a while, and came to a conclusion about how I would have continued it. However, I knew that was not the critique she needed for the sake of the story, so I sat on it for a while, and even discussed with someone I trusted more how to turn my initial critique into helpful critique, and then once I had distilled it down to something I thought would provide her with critical insight, asked if she wanted it.

In that situation, this is my advice. Keep on keeping on. There's so many people out there in this world to talk to yet. You can never offend them all and the best way to learn is to practise! Learn from the interaction, accept there are things out of your control when it comes to interacting with others. If you carry the weight of it forever it'll distract you from seeing the awesome new opportunities waiting around each corner. Forgive yourself.

As for the original question I'm afraid I have no wisdom. The closest relationship I have with a non-family member has brewed over 14 years of stubbornly pestering each other almost every day and going to the weird and ugly places and still coming back out.
