Let's break this down into teeny tiny blocks so you can understand it.
It is possible the Kali loves Alex. The only person that can know for sure if Kali loves Alex is Kali. If Kali has told Alex then Alex would also know.
When a person who you think hates you shows concern about your well being, then the person actually loves you.
You might know that your best friend loves you because he or she pays attention to you when you speak. When a person loves another person, they are often interested in what that person has to say.
Usually you can tell by one's eyes. A person eyes never lie. You usually know when a boy loves you if he checks up on you, respect your wishes, and would like to know more about you as a person. He would like to go places more often with you and last but not least tries his best to be honest with you. Go by your gut feeling/heart.
it's simple...you will just know
that is npt really a question that can be answered... you should just know..
If a person seriously loves you, they will always be looking at you. They will always say hi to you. they will strike up a convo with you. And they will always be nice to you.
A book
i would have to say for me it would be the way the person acts around u if that person acts weird then u know he/she likes u and if they dont care what they do around u then yea ur just a friend
You know the old saying : "If you love something, set it free" Which means, if there's a reason a person shouldn't be with another person, that other person will leave her/him because he/she loves him/her. And, about being mean, a person will get over the partner that left them easier if they are mad at them. Otherwise, they would be depressed and sad all the time.
You just know. Maybe they'll stand by you through everything. You'll know if they do.
Answer You know if someone loves you back by their body rythem, the way they look into your eyes should tell you but if your really don't know, why not ask that person, that way you won't have to guess, you will know.
