How do I always do wrong ?

Hello everyone, I'm 19M autistic from france. I always lived with a dream : find a love.
But as you could guess, if 'im here it's because I'm desperate.
Recently I went here (on reddit) to find people who could be interrested in trying to have a relationship. Even beggining with friendship is ok for me. I'd like to take things slow.
I met various profiles of peoples. went on discord calls with them. But one day to another I'm being ghosted. So I tried for the past 2 months doing that. I tought the problem was langage, like English is not my first language.
Finally I met another french person. We talked (and like always I'm the one that make conversation and find activities). We made 2 calls while she wanted to see me play Cult of the lamb. Then I went to my DnD session and I texted her during the breaks. I've made a spelling error then she blocked me (the spelling error in french is vent (which means wind) instead of vend (which means sell): I was talking about selling things, but right before I was talking about elements.

I want to know, am I the problem. All my past relationships as just finished like this. I'm feeling like a shit.
