Usually, they want to impress you
she likes being next to you even when she could be doing something else that she likes. she flirts with you or leaves her friends to come talk to you then she probably likes you
If someone likes you they will spend time with you, laugh at your jokes, smile with you, talk to you, look at you when they could be doing something else. It doesn't matter who you are, you can always tell if someone likes you.
You don't necessarily have to tell her. You could, during sex, start paying more attention to her feet (e.g: start kissing them or something). You might not need to tell her, if she likes what you are doing then that is all that matters.
If you have to ask the question you are probably being used. If you are not convinced that he actually likes you, what are you doing with him at all?
I think he likes her way deep down, or that he is doing certain things to make them tell that she likes him. I think he is trying to make her tell him that she likes him.
Usually, they'll start doing errands or asking you not to come places or something that they never did before.
Usually if a guy spends time on you, that means he likes you. This could mean teasing you, doing favors for you, talking about you, or just plain talking to you.
Well this is simple all you have to do is do something that he likes that your friend doesnt like doing with him if that doesnt work tell him in person how you feel when they get into an argruement
well you can never really tell but... you can notice something different that they are doing such as talking to you more, complementing you and just being nicer also having the time to get to know you a little more so if the guy is doing any of these i think you should start too and see where it goes:)
try to find who he likes then bam before she can or he can
You might see them kiss. Or something else
If he always stares at you and sits around you. If you like him bach ask him if he likes you before you tell him just in case he does not like you
