"Did I Wrong By Taking Issues Into My Own Hand?"

This real life experience was sent in by an anonymous blog reader. Kindly read and tender your useful advice (if any):

I am an Accountant in one of the leading banks in Nigeria. I married 12years ago. I never had any problem in my marriage not until I told my husband that we need to build a house of our own.
This is how it happened. I brought this idea before him, he was very happy but asked me where he's going to get the money to buy land not to talk about building on it." You know I am not financially stable " he replied. I told him not to worry, that was going to be of help to him.
A month after, my husband told me that there was a plot of land to be sold. We arranged a meeting with the owner of the land and we were taken to the place. I saw this plot of land by myself and I like the area where the land is. We talked about the price, and the owner of the land said the land was to be sold 1million naira.
The following day, when I was coming from work I cashed the money and gave it to my husband as the head of the family, to pay for the land. The money was diverted by my husband for another purpose. I was mad but what can I do as a wife who doesn't want her home to tear apart. I over- looked it and move on with my life.
A year after, I brought the same idea to my husband again because I don't like the bogus amount we spent on rent yearly. I gave him another 1million to get another plot of land. To my surprised, my husband could not account for how the money was spent and did not buy the land. This time around I did not take it easy with him. He knew he was guilty, he begged me and promised not to play on me again. At this junction, I felt I should give him a surprise by getting the land myself. I bought a plot of land without his knowledge and later told him. He did not take it likely with me. He considered me to have taken his place in the family. As I am speaking to you now there is rancour and acrimony in our home because he has decided to back out. How to handle this issue I don't know because it has gone beyond me, and I don't want to lose my home purposely because of my children. I need you to judge me if I was wrong with my decision because, I don't feel I was wrong. Advice me where necessary, and tell me the way forward, plea......se!
