Misunderstanding with my lover

Hi everyone, I request you all to provide me some solution to my life problem. Actually I am in deep love with one girl from many years onwards we both love each other widely. as usual they are certain misunderstandings occurs between any pair. but what my actual problem is I am person with attitude like concentrating more on career only I don't have much interest towards my beauty. as time passes slowly my hair got fallen mostly in time frame of this duration. I got some costly treatment from doctors also but no luck. currently, as time passes slowly misunderstanding between us are increasing day by day. as marriage time is reaching. my girl friend has these problems mainly... 1. how could she project me to his father with my bald head. ( I am getting argue with her as she used to suggest me from more than 4 years to take care of my hair but my career has started with lot of struggles as I am working in software industry lot of new challenges make me bothered to work hard to withstand my career in it. I can't able to balance my career with my beauty. she used to say to balance my career with beauty but only god can understand my situation and work pressure I faced.) 2. she asks me to gather money for our marriage so that she don't want my family prestige to go bad at their family. ( argue between us for this reason is she is questioning me why can't my father take responsibility to financially support to make arrangements for our marriage. what I have given response to her my father can support to some extent as we have some problems and we are from middle class background and also I said if necessary I will take loan from bank then quickly she replied how can I maintain her after marriage If i have taken loan from bank and paying for it after marriage.) 3. I am always open to her. but I used to maintain my self respect to society. now a days she is not liking my attitude asking me to be professional.( what I argue with her is, she is only person in this world to whom I am always like what I like to be. I can show my openness to her itself I don't know why she was not liking currently.) The reason behind sharing my problem to you all is, there may be people who face these kind of Issues with love marriage. and some one also can suggest some solution to me and my girl friend how to maintain our relation in good way to resolve our barriers between us. kindly suggest us best solution to have our relation as good with better understandability.
