Things really changed after our son was born. The touching thing stopped last May. There has been too many excuses as to the fact that she is stressed out over having a child and school. We all do get stressed out. It is a matter of how you handle it.
See, one of things that my W has said that she has changed. I replied, we all change. She felt that she had changed more than I did. I relied that that is ok. Some of her arguments (last May) seem to me to be very loose ones. I told that we are not going to be the same people. Our marriage is going to change as we go through the years.
Another one of her arguments was that our responsibilities as parents are different. I replied, of course they are. I am the father and she is the mother. We both will approach situations with raising our son differently at times. As long as we talk about the situation and come to a compromise.
Going back to the no touching and kissing. I had told W that our ritual kiss goodnight was a way for me to know that she loves me. She took that away to let me know that she felt otherwise. So now, it is not a matter of us having sex. I just want at least our kiss goodnight back. That seems more important to me than sex right now. General human touch as a way to feel connected.
