If you meant "How can you know if your boyfriend loves you when he says it?" Well the answer to that should be obvious. If he really loves you he would express his feelings for you with deep emotion not just a simple "I love you". Now love is a very strong word and has a very strong meaning to it. It gets thrown around too much in relationships which withers it's meaning. To sum it up if he loves you he would show it to you with deep emotion.
He says he loves you
tell him you feelings for him
Well to really tell that he loves you is if he says it!
marry him
Figure it out yourself
ask him how much he loves you
He will tell you how special you are to him. He will want to always be with you. If your boyfriend truly loves you he will tell you "I Love You".
Dear Confused,you tell him that he is moving to fast and to give you some time.Sincerley,Dr.Love <3
love doesnt allow him to get away from you
If you don't want to do it tell him "NO". If he loves you he should respect your wishes.
If he tells you he loves you or by the way he acts
When he says he loves in you in a soft, gentle tone. His eyes light up when he sees you. He can't stand being away from you. And.. you could always ask him.
