+first: If one of you did not wait the 2 years, how would adultery affect the D? Would it change legal positions or does it just speed up the process?
+ second: well, there may not really be a second here. Just thought one thing just wasn't enough...
But really, you told her you would wait the two years (even though it's possible you might find someone new, unless you lived in a cave, in the mountains, with little to no oxygen, and only mineral water to live on...). So she can readily glean from that, you are saying you are prepared to wait for her.
You may not have meant that, but it's there for someone to pull from the words. And so... the ball is in her court. As she has just told you that she can't c either of you (her) waiting two years.
