First of all, a HUGE thank you to everybody who replied. You have no idea how helpful you have been.
I'll try to answer all the questions posed above here. Start: [updated]
1] Not an arranged marriage, but as is common in our culture, there was no sex before marriage. My culture should grow up.
2] The problem isn't only sexual. We clearly have very different emotional values. I'd say this emotional aspect is the other half of my problem. E.g.,
a] Her absolutely not communicating with anyone from my side unless pushed, even when it's a special occasion or a festival.
b] Only last night I got Indian takeout for dinner. I'm suffering from a bad back pain for a couple of weeks now, and I had made an extra bus transfer to get the food. She didn't touch it because she didn't like the looks of it. My efforts to get the food on the table don't really count. In such cases, she explains that she's "just like that". What bull.
c] She crams up the fridge with food and produce that eventually go bad. This happens all the time, just cleaned up the fridge right now. Doesn't care about facts such as millions of people in the world still starve, feels insulted that I attempt dictate her palate by pointing out these things.
d] Would never even let me touch the remote, saying her job is more stressful and she deserves TV more. This stopped after I threatened to break up with her.
3] We don't have any kids, so I guess I'm not fucked in that dept thankfully.
4] Have tried talking, pretty much done everything I could from my end. Still kept up the "dating" mood and took her out for dinner frequently (decided after last night to cut down).
5] Haven't ever cheated on her. Cheating isn't the solution.
6] I always end up feeling like the only one really compromising - emotionally, sexually.
7] It's not that I didn't realize straight into the marriage that we were having issues. I tried talking to her, was always very patient with her, gave her a lot of space (she asked for it), even proposed seeking couples therapy. All that I got every time was ugly fights. Still, I kept on believing that with time she'd grow up. She didn't.
8] She finally started listening to me when I told her I wanted out. Now that our marriage is dissolving, she's finally interested in communicating with me on our issues... but not interested enough, I feel. I can't reciprocate the interest, don't feel interested/bothered any more. Been let down too many times. Can't really trust her sincerity any more.
9] Somehow we're still really affectionate towards each other. I'm no longer willing to call it love though, maybe bad of me?
10] And yes, unfortunately, my story is true.
Have a great Christmas!
