This is your attitude. I cannot change it. Personally, I am a very independent person, and I was raised in a such a way to be independent. I was born in a village and I schooled in Colombo and all my graduate and post-grad are from Colombo universities, and now I live (for my work) in US with my husband. So, this culture issue, I really don't understand. My parents never forced me for a marriage, but they loved me a lot. I lost my dad the day before of final subject in my bachelors. Still, I sat for the exam, scored an A pass and graduated with first class degree. Then I got my PhD and now, I am a Scientist working on research, which is a really stressful thing than marriage life.Compared to what I have seen in this world, I don't think you know even 10% of it. I survived so many hardships to study and to take care of my family even before I found my husband and got married. So, don't assume that I am traditional Sri Lankan house wife, and I don't need somebody just for my survival. If you have seen, what the life is other than the marriage, living a good marriage life is not a big deal.
Talking about my self, working in a country like US, in a high profile and highly competitive job, is a very tactful thing, you have to play a tough role on daily basis specially in a field like research. I think in every job, you have your own responsibilities and duties, which involves අට ලෝ දහම, but you just ignore it. But, when it comes to marriage, it is a big deal.That is how you feel it.
In my personnel life, I don't have to think much, since I made the right choice. I love being home and with my husband, I am 100% myself. I don't know about other people,but I don't depend on anybody, but I do take care and I do love my husband and my family. My husband is the same. Of course, making sacrifice is 100% ok, for a person, who slept in a railway station overnight, when I was hospitalized and for a person who feed me when I am sick, force me to see a Doctor when I am ignorant about my self, who sit and wait to have dinner until I am done with the kitchen, who shares his life with me, and who cares about me thousand times more than I do..Even, if he doesn't do any of these things, for me it Ok to feel for him, since I love him, I do feel his love and he is the only person I can trust in this world except my mom and my brother. Then it is not a business, it is how much you feel for each other. It is like how much you feel for your mom and dad, even if they haven't done anything to you, they gave you the chance to see this world. Also, in my terms, sacrifices are not for the things or people that you are depending on, sacrifices are for the things that you love or that you want to secure for the rest of your life even if you get a zero benefit from it.
It is not being dependent on your partner, it is sharing the life.You are the only person who is responsible for yourself. It is my theory. Home is the only place that you can be your self. But, for all these of course, you have to find the right person, there is no point doing all these for a person, who do the marriage for a business, in sense of money or expecting something back.
I am really sorry if the answer too long, Probably, it is too much about my life, but seeing your comment, felt like writing this.
