Self-Identity v/s Compromise

Thoughts came rushing in after i spoke to A the other day. Her questions, it seemed valid enough: at least in her position they were in place. She said: "I knew i had to make compromises and i did make it but what do i get after those compromises? Ill treatment, fights and some orders to make some compromises? If that is so why do i have to gone on like this? Don't i have my own identity? Before marriage he never uttered a word but now everything has changed"...
Nobody else could understand her situation better than I; but only difference was that she has just got into that relationship and i came out of it long back...
Now, what distinguishes compromise from self- expression?
I think there is a very thin line between the two...
If not drawn properly one or the other person in the relationship suffers...
One should know where self- expression ends and where compromise starts...
One question that always irks me is 'Why always women are expected to make more adjustments than men? Just because they are women? Or to grandiose the idea of women later by saying she suffered so much so she is great?
It's not that men don't make compromises; they do but when they don't nobody asks them any questions whereas if a woman fails to do so hundreds and thousands of questions are asked...
There are of course a category of women who love to compromise to the extent that they lose their own identity and still they are happy about it...There is an advantage with that system: NO FIGHTS between the couple...
But it's not the only category. There are those women who at any cost wouldn't let their self- identity lose and are so not ready make the slightest adjustments...
And there is the third category who can balance between the two...
Education and career, i had thought, would the scene to a greater extent: But how many educated women are able to come out of bad relationships and why can't educated people change their mentality of harassing the woman?
The questions are too many...
I only wish A would find a place and a solution where she could find solace...
