So, like the title says...tonite she left her email open and me being the jealous/curious type I took a peek. At first it looked all clean, until the email that she said her ex "just wrote her recently" turned into a folder I found under her sons name. They range back 3 months, and all this time I had been really sensing that she had been she still denied it. Until tonight, I found an email from the day before my birthday when I was actually put in jail for a DUI in march. At that time when I got out that weekend her story of how it was a busy day and she had to get to work the day before and blah blah, I felt that story to be way too informative for pretty much nothing. So I straight up asked her, you see him? I got a " NO" I was riding the bus and had to go to work and drop the kid off to daycare....well...the EMAIL that night was sent to him asking about the next day if he was going to be downtown, the next email I seen was from him saying, " I really regret not kissing you yesterday" So here it is 3am, i get her up and confront her about writing him...she states what!? NO...I told you that I didnt. (That was until I popped open the emails) Shes starts giving me a sad face and crying and saying sorry...and I just relished....cuz in that time frame, my intuitions were kicking my ***, she was making me feel like I was making it up and going crazy....But basically 63 messages the most current on May 29th 2012...Shes been talking to him through the emails...I was wondering why she was constantly saying that she needed to check her emails for jobs that she applied for...YEA NO SH!T.... My Question...I just booted her out at 3 am, thing is shes lives across the apt lot...like 2 minutes away..haah. I told her Im done do not want to see her ever again, and she kept stating "Oh I love you though I was confused...I know now that I love you...." What do I do?? This is her like 10th time Ive let her back into my life...Im a single DAD, I dont need this crap....What should I do? DO you feel like I did the right thing?? Dam man, I mean the last two ladys I was with ended up just being flakey and flirts/cheaters...I know it looks bad but I mean they seem like the sweetest things on the earth...how decieving....I told her straight up I was a bad boy,but I never once had any urge to ever cheat on her...let alone flirt with another girl.....Im starting to think that there really isnt any faithful real ladies out there....This one was def a sheep in wolves clothing! HELP =S
