I feel like an idiot because it's so easy for me to block him and all but it hurts. 

I met this guy online (through Reddit, actually) and very quickly he had strong feelings for me so after a month we started a not-very-serious long distance relationship. We only speak through text, he's 5,000 miles away. He was so caring and loving and supportive, I was so happy. I had never felt so happy and so in love. But about 5 days ago he said he just can't do long distance and it broke my heart because he was accidentally becoming my favorite person. I've been a nervous wreak ever since, and I'm trying to just be friends with him again but it's so scary constantly worrying over what he thinks of me, if he hurts as much as me, or whatever. 

Here's my options I'm considering:

1. Block him and quit cold turkey
2. Keep messaging him for a few weeks (but being emotionally distant) until my emotions calm down and he's no longer my FP so I can block him easier-ly 
3. Be open about my problems so maybe our friendship could heal and be good friends 

I don't think #1 is possible because a week before we broke up, I sent him a letter through the mail. So that would be kind of awkward if I completely shut him out and then 3 weeks later he gets my letter. He said that he still want to write me a letter too even after breaking up. 

I just don't know what to do. I'm thinking about trying to talk our feelings out and maybe I'll have a clearer decision. Any advice?

Edit: nevermind so we talked and now I'm choosing #1 so like fuck me right I'm such a fucking mess sorry
