How long have you been on the LRT? I feel your pain man, our sitch's have a few similarities. I too am in the midst of LRT, separated since September, and we have no kids together, although she has 3 children of her own, there are few reasons for us to interact. I am new here so I don't have any grandiose suggestions for you at this point, but am interested to hear what the veteran's say about your situation, as it also applies to me. I have two things that are going to force us communicate at some point, one being the car that she drives is mine, and the second being some items I have stored in her garage. The fact that she let me store those things there gives me a false sense of hope.
Maybe a good thing for you would be to "strategically bump" into her more often? Although as I think about that she may think you are persuing/following her I guess...
If you want to look at my posts it will prove that chasing does not work, nor does trying force another man out the picture, I eventually spent a night in jail and got 25 bonus anger management classes as a result of that strategy, when what I was doing was fighting for my marriage, albeit agressively. All in all I don't reccomend that strategy, trust me in that is very expensive in more ways than one. I was successful in getting the other man out of the way, but by my wife's admission if I had handled things differently we would probably be in a totally different place by now.
I feel your pain, and will thinking and praying for you and your marriage and that your situation improves.
