I need Help with a relationship!!?

Alright i'm 18 work and just graduated. one day i met this girl i instantly liked her as soon as i saw her. like i was taken aback when she asked me for my number. that same day. i didn't even know her name nor she know mine so we exchanged numbers. over the next few days we texted and talked some so she invited me over and i picked her up and she's 19. that was the first time i kissed her. and by now i really realy like this girl and i'm still not sure why. it isn't looks because she's really pretty but i've dated really pretty and beautiful before. its not the same thing. so over the next 2 weeks we see each other most nights after i'm off and i get to know her aunt, who she lives with. we both learned some things about each other that should scare away any boyfriend or girlfriend lol but were still here. anyway last week my mother decides shes not good enough for me and that she is using me, because she doesn't have as much money as us. so she gave me a choice to break up with her or leave. i really need to stay at home for the time being while i go to school and stuff. so we talked this over me and the girl. and she decided we better call it of for the better, that i dont understand now but will later. so i was upset and she was too. so the next week goes by and i stop by. we talk bout everything and how i got everything straightened out and if we could basically go back. she cried but said she wasn't quite ready for a real relationship. which i understand because she is working on her ged. taking care of her sick aunt and helping her run her business while taking care of her little cousin too. so i mean we only saw each other at night. because i worked and she always was busy. this was last week. also we kinda promised each other then that we would try again later down the road. now i check my phone and she left a message sayin somethin. i cant really understand but she's upset. which is really hard for her. she's a tough girl. but anyway idk what to do. no we haven't had sex and i think i love this girl. i;m bein honest. i've never felt this way about anything... but idk what to do should. i call her. do nothing, forget bout her, or wait another month or two and show up.... idk
