Hello - please can someone help!

Hello - I'm very new here, and hurting very much at the moment.

My wife of 29 years has had a year long affair and is threatening to walk out on me. I can forgive as I love her and also don't want to lose everything we've built up over this time. Also, I've just come into my inheritance, and she could walk away with half of it (I assume). Her inheritance will come one day, and I'll have no claim to this.
Can anyone suggest what options I have. Do I have to agree to a divorce, or how long a period do I have to spin this out. I've read somewhere it's 2 years, but then, I've also read it could be 5 years. PLEASE can anyone help. This is a nightmare to me, my whole life and dreams for the future possibly shattered forever!

Thanks
