Your "friend" doesn't sound like a friend, the guy you like sounds like he likes the attention of the both of you too much to give up flirting, so isn't interested in a serious date/relationship.
If he asked you in a joking tone then that means he knows you are interested in him and you need to put the moves on him. If it wasn't in a joking tone then he is annoyed and probably likes your friend, in which case you should try to compete with your friend by spending more time with him and flirting more than she does.
well i think he likes you more than a friend if he is flirting and doing all of that
most likely, he is doing this so that you will in turn be jealous of him. He just wants you to feel the way he feels.
you know if he keeps doing just to get your attention, and if you get mad and upset then it means your jealous
Make sure you know his intentions. If he openly flirts with you but is dating your friend, can you be sure he won't do this to you? If so, then is he worthy of you? It's true that you should find out if he is doing it to try and date you, he may only be flirting for fun, if it is just for fun then and you think he is being inapropriate, just tell him that and to tone it way down. If he is trying to get a date with you, the person above is right, you should watch out for him doing the same to you
if she is truly your friend talk to her about it.. if you have already talked to her about it and she is supposedly "unintentionally" flirting but she keeps doing it.. its not unintentional anymore.. so talk to her about it and if you already have then stop being her friend..
No, as long as you are not doing anything to it, or checking their texts and previous calls obsessively.
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
Of course not! She is his sister. He has absolutely no romantic feelings for her at all. You should only feel jealous if a woman is trying to steal your husband. Obviously his sister isn't doing that.
flirt just a tiny bit and if he kinda flirts back thenkeep doing it and see where it goes if it goes nowhere then he simply doesnt wanna be more than friends
I would say you cannot. If they are your friend with benefits and you have the other person has absolutely no other interest in you but sex, I don't see it possible.
There's a possible chance it could mean that but it doesn't always mean that. Ask her if she likes him.
