This is a really long story so I'll try to summarize.
First of all, I know I will be judged for this but you have to believe I don't intentionally want to hurt anyone involved. I can't help how I feel.
I've been married for 7 years. My wife and I drifted apart over the last 2. We are not in love. I don't know whose fault it is. Maybe mine, maybe hers. At this point it doesn't matter. The point is, we were basically living as roommates, and the lonliness affected her more than it affected me. She became unfaithful.
After that, I became angry and jealous even though we were obviously not in love, which was strange... in any case, I was depressed, and I started talking to a female friend from the past who had been through something similar with her ex husband. We started talking a lot, even met in person a few times. I had always had a thing for her, even back before my wife and I were married. I fell pretty hard for her once I started getting to know her better. I kissed her once. That was the extent of our physical relationship. She admitted that she was crazy about me as well but couldn't let it go further.
Then she moved out of state. That was when I kissed her, because I thought to myself that some day, when I die, I didn't want to die without knowing what that would be like. But after she was gone I started missing her like crazy. Even my wife suspected that I was in love with her because it was affecting me so visibly.
I started acting like a jerk towards her (my friend). I was obsessing, thinking about her all day and all night. Dreaming about her. No joke. I have a feeling of despair that is so overwhelming that I just want to start screaming at the top of my lungs and breaking shit because I can't have her (I never have done that, nor will I, but it is literally that intense). We went back and forth a lot, fighting and making up. Trying to be just friends. I know it was my fault. I acted like a crazy person, because well, I'm crazy about her. But apparently I went too far because even though I apologized she hasn't spoken to me in almost a month. Now I don't know what to do. I am still married, but I have no feelings for my wife like I do for this woman. I feel like a horrible person.
I keep telling myself that I just want her (my friend) in my life, even if it's just as a friend with no possibility for anything more. But I know that if I had the money I would hop a plane right now to go see her and leave my whole life behind for her. I must be stupid, or crazy. I can't deal with this. Although apparently now I have no choice because she's not speaking to me anyway. I hate this. My happiness should not depend on another person like this. It has to be unhealthy. What should I do? I'm asking the women because I want to know, if you were in her position, and I kept going back and forth on you, saying I would just be your friend and then getting mad at you for not being in love with me, that must be a turn off, right? How many times would you forgive me for that? Will she ever get over it, or did I blow it? Should I even be worrying about that, considering the state of my marriage? I feel like a hopeless wretch of a man.
