text: how do you know when youre really in love??? i think im falling in love....ive been going out with my boyfriend for a while now. 5 months i think. and i want to love him, but i dont know how to tell when im sure. there is no way to tell if its real or not, you'll know when you are in love. dont force it, give it a chance to grow. when it does happen, you wont have to ask, you'll just know
