If the only answers you get from your wife are "I don't know" & "I don't want to talk about it now.", that is NOT communication. She either has a serious problem communicating or she's not wanting to be honest with you. Either problem makes a good marriage IMPOSSIBLE.

If you could find a good marriage counselor & you are both willing to work on making the marriage work because you care about each other & not just for financial reasons then you might get somewhere.

I lived for 33 years with a husband when asked a question how response was either "I don't know" or "whatever". Honestly by the time I finally did leave I was seeing red any time I had to have anything to do with him.

I left him 9 years ago & moved 2100 miles away. Gave him one chance to get his act together at my new farm I was able to buy after my mom died. Problem was that with the economy & finances, I haven't been able to afford even the low cost divorce. I have no interest in ever getting married again or having a guy in my life again after all those miserable years so the only reason I really need the divorce is to protect myself from his financial irresponsible behavior.

He was never capable of communicating of any emotional connection. Didn't realize the real picture of the relationship until after I left & was able to analyze all those years & realize that I left my problems with him which made me realize that I wasn't the one who was causing the problems in the first place.

Maybe your wife isn't communicating with you because she doesn't want to hurt your feelings by being honest but it sounds more like her inability to communicate. Probably best to just end your marriage at this point rather than fighting & battling to make something impossible work when in the end you will be miserable anyway.

I believe in the marriage commitment but after my own experience, I do believe there are reasonable exceptions.
