<human>: So my current girlfriend and i started dating about 3 months ago. I have been perfectly happy in this relationship up until a few days ago, when me and my ex girlfriend came into contact. 
My ex and i dated for about 2 years and haven't talked in about a year; she was my first serious relationship i ever had and vice versa. Last week i was visiting my hometown from college and she messaged me and we decided to catch up one night.
Before we hang out we exchanged snapchat names and she said some sexual things to me, but not directly. One was her saying "she had some needs to be taken care of" and she was messaging me first almost every day before we caught up.
So the night comes and we hang out and dont really do anything, we just talked and i was there for a few hours. Now I am thinking about her more often than i should be, i had a dream about her, and sometimes when i get a snapchat or text, i hope it is my ex instead of my own girlfriend. 
Now I am in a situation where i have a perfectly amazing girlfriend but I'm about to blow it for a girl that might not even feel the same way. She barely talks to me since the hangout and i want to tell my ex how i feel and i want her to want to talk to me everyday again. its driving me crazy. 
I know i am young and this is probably dumb to most people, but I am usually very clear on my emotions and i feel confused for the first time ever. i want both and i know im going to either have to deal with losing my ex or hurting this girl i am with for no reason. what should i do reddit?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I have a great girlfriend but reconnected with my first serious ex gf and now i have feelings for her again and do not know if they are even mutual.
