how would you know if a man really loves you?

at first, i thought that long distance relationships won't work. but my boyfriend and i's relationship is doing great despite the distance. he came over to visit me and my family. he showed respect to my parents. he treated me like a queen. he pampered me and showed me loyalty. he's my lover, my friend and he listens. he sees me. he wants me. and he needs me. maybe you'll know if a man really loves you if he will never ever try to cheat on you... that's respect and loyalty.
