Why do I get jealous over a girl even though I don't want to be with her at all?

 It is important to note that body language can be complex and ambiguous, and it is not always possible to accurately interpret someone's feelings based on their body language alone. However, there are some general body language cues that may indicate that someone is interested in you, even if they say no.

Some of these cues include:

Making eye contact

Smiling

Touching you lightly on the arm or shoulder

Leaning in towards you

Mirroring your body language

Playing with their hair or jewelry

If you notice a girl doing any of these things, it may be a sign that she is interested in you, even if she says no. However, it is important to respect her wishes and not pressure her into doing anything she is not comfortable with.

It is also important to remember that girls have many different reasons for saying no to a guy. They may not be interested in him, they may not be ready for a relationship, or they may simply not be in the mood. It is important to respect her decision and not take it personally.

If you are unsure of how to interpret a girl's body language, it is always best to err on the side of caution and not assume that she is interested in you just because she is giving you mixed signals. The best way to find out if she is interested in you is to ask her directly.
