Me and my boyfriend tell each other we love yous every day about 50 times a day. But at the end we always say I love you more or something like that, and tells me to prove it and I don't know how. What do I do to prove to him that I love him?

I mean we write notes and sweet things like that to each other. I just have no ideas?

He is just messing with your head. Tell him to lasso the moon to prove his love.

Have you had sex with him yet? Usually, when a boy, any age, asks to "prove it", he wants to have sex with you. Anyway, you have nothing to prove. If you both really do love each other, he should not be asking you to prove it. As the other answer said, he is just simply saying something to throw you off. Tell him you don't like it, and to stop. If he doesn't, then I would start looking around, and meeting new boys. Be honest, and respectful to others, and you will find someone who really does love you.

I willl agree with samcreed on this one, the "prove you love me" is a code word for have sex with me to prove it.

Next sorry but start talking and start saying I love you less, saying it all the time cheapens it.
And unless you have dated for a year or more, you are in "heat" from hormones, attacked by sexual desires and real love has little to do with it.
Real love does not have to be proved (EVER)
