You can LIKE him a lot.
But you cannot LOVE him until the two of you have been living together as partners, for at least 2-3 years.
Right now, you CAN become infatuated with him, but that is not love, that is nothing LIKE love, that never lasts, and when it dies out, the stronger the infatuation was in the first while, the worse the relationship will be.
As hard as it is to see it now, no one is perfect. And the longer you've been with them, the more you will notice this. And the closer you become with them (investing hope and lifestyle in being with them) the more what they do will hurt/anger you. This IS how relationships are.
It takes about 20 years of marriage for someone to figure out how to work with their own emotions so the relationship will work well. And even then, the fireworks die out (although from time to time there may be brief sparks) .. what happens is that you become partners and a source of comfort and well-being for each other, but none of that initial excitement you felt during the infatuation phase.
He is moving too fast, and that is a BAD sign. It means he is investing in a fantasy about you, and once the infatuation/fantasy phase dies out, he will be bitter that you are NOT his "dream".
An emotionally-healthy man takes about 12 months of steady dating before he decides if he wants to spend the rest of his life with a girl.
And an emotionally-healthy female runs away from men who move too fast. They know that he is playing at being in love, that his feelings are for his fantasy and NOT about her, and that his feelings will die out so she had better not buy into them.
But if we have low self-esteem it is very flattering to have someone fall hard and fast for su.
