I appreciate everyone taking the time to reach out and give such detailed advice. I spent a week away from this site and the internet in general to give myself some time to really think about how things went wrong. The bottom line is simple. We have spent our entire adult lives together and only knew each other. I foolishly didn't think this through when I encouraged her to be with someone else, and obviously she found something she believes is far superior to me and more satisfying and she couldn't walk away.
I just hope for her sake that leaving me for a 29 year old guy, who's never been married, and who carried on an affair with a married woman doesn't end up biting her in the ass, but that is no longer my problem. She has chosen him over me and our marriage.
After paying $250.00 for one hour with a lawyer, I agreed to the unconstested divorce she offered and on Wednesday of this week, signed the papers. The Attorney who advised me said I would be foolish to reject this deal as she is walking away from everything, including our martial home which has equity in it, my 401K, and household furnishings. We have agreed to equally split our savings, and what monies are in the joint checking account. I am told by my lawyer that the divorce will probably happen in as soon as 30 days. Just waiting on a court date.
I still struggle and don't understand why she had to rush this. I was hoping for some time to try and work things out. I was even willing to agree to a separation to ensure this is what she really wanted, and give her time with him, but what's done is done.
I am now back in the house. She moved out after I signed the divorce papers. I asked her via text where she went but she ignored my question. I can only assume she is living with him. I do want to know though because it will make me feel better knowing she isn't alone.
I am devastated and heartbroken, and I will miss her in my life, but I have no choice but to accept the cards I have been dealt. I have an appointment next week with a therapist. I am going to need the guidance of a professional to get over this loss and the guilt I have to go along with it.
I want to thank everyone here who has reached out in the comment threads and by personal message. The support has helped me and my family is really stepping up to the plate as well. I also want to thank the group administrator for allowing my post. I do realize this is an unusual situation, and posts like this are probably not the norm, but posting here and receiving all the advice/support has helped me greatly and for that, I am extremely grateful.
