How am I supposed to understand that (girl)?

The following situation, I've been really good friends with a girl for 3 months. I have told her many times that I only like her amicably because she is really nice. She was with me recently and we smoked a pipe, cooked it and watched Netflix. But now it was so that she made herself really chic when she was with me (leather pants, well made-up, etc.). When we watched Netflix together, I felt that she was very excited and also had a fast heartbeat. Although she only means that she likes me amicably, I don't really know because of all the signs. But I have no desire to try anything with her because I'm afraid that I will interpret it incorrectly and then she will break off the contact. How would you interpret that?

I think she likes you more. Otherwise she wouldn't be so excited and her heart wouldn't beat. She wants more from you. It is the case with many girls that they like their best friend. (Unfortunately)

I can imagine that she wants something more than friendship from you. Otherwise tell her something sweet or a compliment and see how she reacts to it.

I would meet her again to watch netflix and look at her with a great scene and try to kiss and if she wants to kiss you then things will happen on their own

I also believe that she wants to communicate with you in the physical sense. If you do not want such a contact you should say it clearly, at the risk that you will get rid of it. Otherwise: dare and have fun!

Attention! That could be embarrassing. There are many reasons for a girl to prepare herself:

a.) She was at an event.

b) She just likes to run around like that.

c) She was on a job interview, exam whatever.

You can try it with her, of course, but be careful if she doesn't want anything from you.

No, she only met with me that day

Oh, well then…
