That’s needy behavior. That’s going to turn her off.
She doesn’t want to have to act a certain way in order for you to be happy or in a good mood. She just wants to have fun hanging out with you!
So drop looking for ‘signs’ from her. Focus your energy on being in a good mood while you’re around her. that’s what’s going to make her attracted to you.
Think about it this way: if you’re hanging out with her all the time, and she laughs at your jokes, and wants to spend time alone with you, then those are all already great signs! She enjoys spending time with you, dude! That’s what you want!
Women want to date guys that they like spending time with. They want to f*ck guys that they like spending time with. They want to be around guys that make them feel good.
So keep doing what you’re doing. If you’re attracted to her, don’t hide your attraction. Own it. It’s nothing shameful or embarrassing, you think she’s hot, you like hanging out with her, and you want something more than a friendship with her. No woman is going to sense that and think “what a creep”.
