It’s not about the things they buy you, the more money they spend the more they love your; you can’t buy love. It’s about the simple things in life that you can’t put a price tag on. Like affection, consideration of one’s feelings, putting your needs in front of theirs; making sure you are warm even if they are cold. Those are true signs someone loves you.
You can tell if someone really loves you if the person makes you laugh, and is considerate, kind, respectful? Does this person treat you well? Does this person show affection for you, do things for you even if it may inconvenience them? Answer those and you will have your answer.
You know when a person likes you if they really care about you and they are allways there to catch you when you fall. They allways tell you that they love you and that they wouldn't switch you for anyone else!
