Thanks for the advice. This is killing me on the inside. Im finding it very hard to accept that it has come to this. I told myself it was a bump in the road, that we were strong together. We have been through a lot together and I cant imagine being without her.

I should clarify that we have been intimate in the last 3 years, just not as we were previously. Our sex life dropped to around once every two weeks, if that. Pretty crappy. That didn't help my state of mind with things either.

Im really concerned at how she became so suddenly detached from me, almost like she is a different person in an instant.

She was talking a lot about her work this morning. I was listening intently and at one point I felt bad for the position she was in and my face reacted accordingly. Somehow she took this as a negative and said she should stop talking about work with me so much because I looked like I was fed up of hearing it. I quickly explained that this was not the case and that my face was simply sympathy for the position she was in. She accepted this and I then said that 'thats what Im here for' etc, etc.
She then hit me with the 'you haven't wanted to hear about this stuff for 12 years' line which I found rather hurtful but I have to accept that this is how she sees it.
We have had a lot of great times but she is totally focusing on the negatives at the moment. Gotta put my feelings aside at the moment and keep pushing on with the new me.

Told her I was going out tonight and she didn't even ask where or who I'm going with! Just said 'go...you should do it'.

Going to stay so strong for my kids but wow, this is incredible.

Even if we get through this, Im worried that I will be always wondering if this will happen again regardless of my efforts.
