Okay, My girlfriend and I have been together for 10 months. I really love her and I feel like she really love's me. Anyway, the other day my girlfriend and I were drinking in our living room and we were sitting on the couch watching Sweeney Todd. Half way through the movie/musical I noticed that she was texting. At one point, I glanced at her phone to see what she was texting and I noticed that she responded "AM". For some reason, that really caught my attention and I discretely grabbed her cell phone and told her that I was going to the bath room. Once in the bathroom, I began reading all the text messages and noticed that it was a guy she was texting. To this "guy" she texted "It's ok, my guy works in the morning and I don't go to work until 5 PM so I am spending the entire morning by myself." the guy then replies "so when can I go over?" she says, "Tomorrow at 9" the guy then asks, "AM or PM?" she then says "AM" then she added "we can smoke, chill and lay in bed."
Since I was practically drunk, I read every text message very carefully before going to the living room and blowing up on her. It made sense to me and I went to the living room to confront her. I asked her what the fuck that was about on her phone and she said to me that "it was a joke, I noticed that you were looking at my phone the other day, so I planned this out with my guy friend that I know way back from High School. It's NOTHING, it was supposed to be a joke, I didn't think you were going to take it this way...."
Well, after that I left the living room thinking about how well she knows me and how I would get if I were to find something like that. I honestly feel like that will always be in the back of my head whether it was a joke or not.. Since she says that she knows the guy from high school I figure that she wanted to actually do something with the guy and since she got caught before doing the deed, she played it off as a "joke". So I also ask myself, "What if I would've never taken the cell phone and read the text messages? Would it have happened or what...?
My question is..was this really a joke and if so, why joke like that, knowing that this will probe my trust for her?
