You can't be sure, since guys lie about this all the time. Best is to look at how he treats you. Does he treat you with respect, as though he likes you and enjoys your company, is he interested in what you have to say, is he kind to you, before during and after sex? Does he consider your needs and interests? Is he faithful and honest with you, or is he only interested in you for sex, lying to you and flirting with other girls? Good luck. Okay, this is what I think how you can tell if a guy is in love with you. He is interest what you have to say, he say hi to you alot, treats you with respect, being honest with you, he looks deep into your eyes, and he laughs at your funny jokes. At the moment I have a boyfriend and I know he loves me because he said it to me and I replied back to him "I LOVE YOU too".
if your a guy and your friend is a girl how can you tell if she is in love with you?
