HELP!!! my GIRLFRIEND was CRYING?

From a girls point of view you need to be very loving and caring of her which from your details it seems like you are! But she just poured her heart out to you and I'm not saying you need to do the same but tell her you love her or that she your world because she needs to know that you love her as much as she loves you. Don't be freaked out by it because girls are normally very emotional beings, you just have to get used to it. But let her know how you feel soon are the relationship will end up being awkward and bad. Best of luck!
