Romantic relationships

Hi guys, so I have been thinking a lot about romantic feelings, and I just don’t understand them. 

I tried to talk with my friends (they are not autistic) and I still don’t understand. The hardest part to me is understand what is the difference between liking someone as just friends or something more. The only conclusion that I got is that romantic feelings sometimes have physical contact. 

But I still confused, I really like hugging my friends and I don’t know how I fell about kissing….

There is this one person who has been making me confused, she is autistic, and I just met her so I’m not sure if I have romantic feelings about her or I’m just really happy for meting someone who gets me. 

What do you guys think? Any tips about this topic??
