Lost my job & wife behavior changed.

Me & my wife and a daughter have been together for about 6years. So after college I became a father and after finishing my studies I took looked after my father's business and some what supported my family who lives with me(lets say 5 months a year). My father kept on telling me to finish my studies and complete my degree since I was only a diploma holder. I took his advice and joined University, few months later he passed away and the business had to be shut down. Though he left some money for me to complete the studies. I supported my wife & child as long as the money was there. Now that I have completed my education, I have been job less for about 7 months, its just those cases when 'its not what you know, its who you know', but still I am doing my best to find work. I understand what she is going through & paying for daughter's school fee but I see & feel degradation in her attitude towards me. Since we both don't live in the same country, I requested if she could pay for my ticket and we could be all together. I feel in her response that even if we are together or coming to live with her, I will be just a responsibility on her to take care of since I will be coming with no money. I never confronted her about her change in behavior but it just shows the way she talks to me now. Any help how to deal with this? or all this is just in my head?
