<human>: Provide a brief overview of the text.

Okay so Louis (the girl I'm talking to, she's 17. btw you pronounce it like Stewie's mom) and I (male, 16) talked for around a week and a half. Everything was going great, superb! Until, her ex comes along. We'll call him Satan (17, male).

 Satan and Louis dated for a while and broke up not long ago. Louis was pretty crushed because Satan cheated and lied to her through the whole duration of the relationship. They were done, as far as I knew. Satan decided that he wasn't done with Loius, so he proceeds to do absolutely ***everything*** he can to split Louis and I up. He told her lies about me, told her bad things from my past, and etc etc etc. 

Louis and I stopped talking because Louis decided she still had feelings for Satan. Three days later, she decides to come to me saying how she misses me and likes me and such. I told her I missed her and then I did something I probably shouldn't have. I kissed her. Not on the lips, on the cheek. A kiss, nonetheless. Well, she doesn't know whether she wants me, or Satan. She realizes that Satan is horrible for her, but he was her first love and he will always have a special place in her heart. Unfortunately that special place is a little to big, and its interfering with her and I's relationship. 

Reddit, what should she do? What should I do? What should *we* do?
