I am 29, my wife is 30. We have been married for 5 years and have a 7 year old son.
Further to recent events I have told her that it is time to separate. I was deeply unhappy in our relationship but was unfaithful to her one day about 7 months ago.
Prior to this I had been unhappy with the way she handled any conversations about difficult issues that may evolve such as money and our son. She would always shut me down at the first opportunity whenever she was unhappy with something. This had gone on for years and it just left me apathetic towards her.
In any case, I expected my wife to end things after I told her about my infidelity shortly after it happened. However, she wanted to carry on.
Even so, the same feelings I had remained for a while. After a few weeks, we started becoming friendlier again but further arguments occurred. She was frequently looking at my phone which I can understand but I said that at some point this has to stop, and it didn't. Similar arguments to before also occurred and so I have just ended up feeling apathy once again and declared that I want to separate.
Once I did that she told me that she was pregnant. I didn't/don't know what to think in regards to the dynamic between my and I given the circumstances.
I still don't feel for her like a partner should.
Any general advice would be appreciated. (I know some people will think that I am out of line but constructive advice would be appreciated all the same).
