I agree with Joe1981. I've been working away from home during the week for two and a half years and in my opinion it has driven a huge wedge between us. I'm looking for a job nearby now.
I'm also not convinced NC is a good idea. She could get used to that. I was virtually NC while I was away even before BDay as there wasn't really anything to say: 'got up, went to work, back to the flat, went to bed' isn't newsworthy. My wife used this as evidence against me that we've drifted apart.
I wrote a response earlier but it's not been authorised by the mods yet. Basically, I do not work away from home - my job involves travel for extended periods of time now and then.
Also, the NC was my wife's request, not mine. I was initially against it but she said she needed it to assess what she wants to do (stay or leave) and hopes to rekindle some sort of emotion for me through absence. I'm simply respecting her wishes - she knows I don't agree with her.
