My ex-girlfriend and I were together for 2 years and we had lived together for almost 6 months. We had a great relationship and had talked about the future and possibly getting married. Two weekends before our 2 year anniversary I had to go on a business trip. On the trip I had a One Night Stand with a girl who was working at the lounge I had gone to after my business meeting . It was a mistake and I know I am 100 percent to blame. She was a good girlfriend and I am man enough to admit it was pure selfishness on my part. Afterward I felt terrible and vowed to commit myself to my girlfriend and never do it again. However 10 days later on our actual anniversary when I got home from work she was gone. Everything was normal when I left and she even told me she loved me and kissed me goodbye. Her stuff was all gone and on the living room table was her cell phone (with the memory wiped) and a picture from the hotel surveillance camera of me and lounge girl in the lobby together. Fark. No idea how she found out, I was on the trip alone in a different city, lounge girl and I only gave first names, I didn't tell her where I worked and we never exchanged numbers or anything and the hotel was paid for by my work.
Still I figure she would cool down and then we could talk about it, but I haven't seen her since the morning of that day. That was back on November 10. We were due to renew the lease on our townhouse at the end of November but I ended up having to move because I couldn't afford the rent on my own. She left her phone behind presumably because we were on a couples plan that I was paying for. So I don't know her new cell number to call her on. She has blocked me and all of our mutual friends that we made as a couple on Facebook and when I email her it gets bounced back as being undeliverable. If I message one of her friends or family on Facebook I immediately get blocked without reply. She took her name of the joint bank account even though she left all the money and her mail is being re-routed from our old town house, and the post office can't tell me where due to privacy reasons. In short I have no idea where she is living or how to contact her.
The only 2 things I can think of is either going to see her at work or hiring a PI to find her. She works in a hospital emergency room, but because it's behind closed doors separate from the triage area I can't just walk in and go see her. I can't call her directly there, because the number is internal and there is a switchboard.When I call the switchboard I'm told she is not available and not given the option of leaving a message. I also sent a apology letter to her work and it was marked as return to sender unopened. She didn't have a car, we shard mine so I have no idea if she has a car or how she is getting to work and around, so it's not like I can wait by the employee parking garage and follow her out because I have no idea what she is driving. A PI is expensive but I think it would be worth it because I really want her back. When I got into PUA it wasn't so I could have a bunch of girls, although I did do that for a while, it was so I could get over and my anxiety around women and meet a women to have a future with, which I did. I know I'm the one to blame but I know if she would give me a second chance I could make it up to her. I also know she still loves me and I don't understand why she is throwing everything away over one stupid mistake. Please help, any advice on what to do in my situation is appreciated.
