would you call this grounds for the big D?

My wife hardly answer her phone when I call. She does not pay for the service and has not paid for her own phone I covered all of that. Got her a phone because she said we needed to have more lines of communication. I call her when she i know she is not at work and not sleeping and she said she does not answer in front of company because it is rude. She has one friend. Complains about her family calling when she is trying to sleep and see her answer their calls all the time.

Reason for this rant. she recently called me to tell me her car is not working, I now live in another Town 2 hours away there is not much I can do. She told me the symptoms and I told her what i think it could be, but not certain due to the fact I can not see what it is doing. Told her what I would do she did not like anything I suggested, and it took her a long time to get it back home. we left the conversation when she said she was going to the number of her mother, which lives a stones throw away, number of her Mechanic. Told her to keep me posted.

I made a few call of friends of mine to get their take, some work turning wrenches, they told me what they thought. when I tried to call her back no answer, Text her, even though she hates long texts, she still has not responded. I have called four times and texted once with in the period of 24 hours. Still no call back. I am not surprised she does this all the time but she often tells me to call her because it shows I care, and I have told her many times she never answers or calls back and it aggravates me so that is why i do not bother, and I do not care for her not answering or returning calls.

So my question who would put up with this? Tired of trying to make this thing "work".
