last night she wanted to go to the movies to see the matrix, and i siad no, cuz i already saw it for cheaper then i would be paying to go see it a second time (fucking $9.50+). She then says " You Promised.", I still said "no", shes like fine i am going to hang out with my friends at there house. I said fine, be back at a desent time. So i go out with my parents to dinner and we get back. Its only like 730 pm. so i stay down stairs until 845 pm. and call it a night seeing how i have to be at work by 545 am. i wake up at like 1000 pm and she isn't home, then again at 1130 pm, and then finally at 145 am when she walks in the fucking door. Ok get this, last night she didn't get home until 1145 pm. and the friands she went to has an older bro. which is kinda my friend, and another friend of mine. And the other day he wanted us to come over so we could all get drunk take in mind that i am 19 and my gf is 18. well she went there last night and since she didn't dome home until early that morning, I bet she was up to something, like getting drunk and then possibly doing other things i don't need to know, and that shouldn't happen. and get this that other night when she came home at 1145 pm. I rolled over a gave her a hug kinda and i thought i felt dry cum on her. Fucking gross, i mean it was on the other side of he so i couldn't have don't it. And I would have rememberd something like that. Well, i need help on how to approach her about last night and the night before? I ask things all the time and she always denies them. but she has done things in the past and said she will stiaghten up but I don't think she is. help me quick guys!!!!!
