Repetitive talking in autistic adults

Hello, I'm 23 years old I diagnosed with Asperger's recently, so I didn't get the necessary early intervention I facing difficulties in social interaction, talk, communication and also I don't have any friends, when I trying to make friends I keep talking only about the things I care about without stopping I can't stop myself and I don't like to listen to The things that I don’t care about, so the person I talk to gets bored of me and his friendship doesn't last long, then I suffer for the loss of the only friend, and then the suffering begins again with another person, as I try to get friends and at the same time I hate social relations.
Can I get your advice and how can I stop talking about the things I care about only without being able to stop and thank you all

  • I dont know if this helps but I have the same problem so what I do is I kinda set a time limit on myself for how long to talk about something.

    If I am talking about one of my interests I try to stop after 5 minutes. If the other person hasnt shown any interest in talking back I will then ask them a question about themselves, like what sort of weekend they have had for instance. 

    I used to talk about my interests all the time but now I do that cos Im worried about boring people
