Wife walking away

[LBSinTX]

When bomb was dropped I didn't resist. I said it's for the best. I apologized and took the lion's share of responsibility. After all, I'd been the focus for so long. I'd been fighting very hard for several months to make her happy and I'd been reading advice online before I found this site. The advice I read was to not resist and play it cool. Likewise, when it came to divorce talk I didn't resist and we talked about agreements. Now, I believe she knows that I don't want it and I've read a lot on MLC and am certain that's what is going on with her. I do acknowledge what I did to contribute to the problems in the marriage. I've gone dim. We still chat when we see each other briefly. Somehow, though she seems to steer us into an argument. So, I'm trying to detach and want to limit contact but not go completely dark. We have kids together. My question is whether or not I should express at this point that I don't want the divorce or express that I want to save our marriage. I'm afraid she'll see me as waffling and now throwing down some road block and it will enrage her. Any advice?
