(Don't worry about being a man here, I'm one too).

I'm sorry to say, but I don't think their is any easy answer for this considering where you are. You already have 3 things stacked against you. 1. Caste, 2. Religion, 3. Family choice. You could possibly get around caste maybe if you were able to find a job that puts you up there. But you still have the religion issue, as I'm not sure which ones but it doesn't matter because their not the same. We have the same issues in the USA, but the only difference is we're more spoiled here and do whatever we want without too much consequence. Try to understand her position is a bit more serious than her. Being a woman he has much more pressure on her to be obedient. I don't know if she would be in danger but that's a great possibility. She may choose to "spoil" her life because it's the only possible option she would be faced with. I wish I could give a good solution, to this, but unless your families were willing to be more accepting of the situation, there probably would be no way around this. The only options I see is, defy your families, which would end in shame, and possible danger (again I'm not sure what goes on there at this point and at what lengths people would go to protect honor). The other option would be to run away together, which would end in the same result. Considering finances is a real issue, this may not be an option. The more realistic options would be for both of you to wait it out, but this would not be likely. Unfortunately, the only option may be for both of you to try your hardest to move on. I'm sorry.

Your story reminds me exactly of Romeo and Juliet- have you read this play or seen the movie? You sound like a true romantic at heart, and your story is very sweet. But I have to ask- have you ever actually met her in real life aside from just talking on the computer? Because if you have not, it is very, very difficult for me to believe that you really love her. I don't understand how it is possible to love someone if you have never met them. But that is just my opinion. Onto the other issues you mentioned, I think that if you had a decent job this situation may be a lot easier, as her and her parents would know that you would be able to provide for her and any future children financially. I don't know her parents, but I think that if you had a good job, it might be easier to overlook other issues such as different religions. It makes me really sad to hear that her parents don't seem to care very much if at all if she even likes the man they want her to marry or is even ready for marriage. I thought that perhaps the Indian culture had evolved a bit to at least take the women's feelings into consideration. In terms of work, have you thought outside the box in any ways? What about opening up a website? I have heard this can be very lucrative. Have you considered moving elsewhere where jobs in your field may be easier to get? Is there any way you can complete your degree faster? If your lack of a job seems to be the biggest problem right now, I think you should work on that issue first. Now, if you do get a good job, will the odds of her wanting to marry you increase? I think you should ask her this. Does she think her parents will be easier to convince if your financial situation was better? I hope that things change for you, but I am not sure what I could say that may help. I think that these things have a way of working out if they are really meant to be. If you 2 are meant to be together, then you will be. If not, realize that there are many other women out there that you could love and be compatible with.
Good luck to you.

we have met lot of times in real life and are very much in love... we are havin long distance relationship, she resides around 2 hrs distance from my place, and we meet whenever its possible, Ya I havin decent job may improve our condition but problem is no job available for fresher due to recession, And s i told before i have job in hand in very good company so i have to wait for that only and it may take 6 months to join... So life in mess.........

hey hi i know ur problem is quite big but it can be solved in a way give them such a proposal them before even rejecting they have to think hard like if u get such a job that can pay u more n that too very handsome amt then things can change n it can favour u but for that ur lady love have to support u in a way that she have to make her parents understand or wait for the time u get a good job n for that u seriously have to make potential efforts n i believe "don't fail before trying".
