Sometimes in life, it helps for me to think in terms of eternal recurrence: if you had to live your life exactly the same way over and over again for eternity, how would that affect the decision you are about to make? (no past decisions, they're already done and gone) The idea is to put into perspective how important the decision is for your life, your happiness, instead of succumbing to some other pressures we have in our lives, which may be superficial and not that important. If you're having concerns on whether it's moral to go your separate ways based on physical attraction, I think this is the wrong perspective; that's an idea based in social pressure ("Will people think I'm a bad person for/Am I shallow for..."). A more appropriate concern is whether or not you can stay in a marriage with no physical attraction. Everyone is different when it comes to how important physical attraction/interaction is to them, so just be true to yourself. Life is hard, so also cut yourself some slack and show yourself a little compassion. Life isn't linear, either, and sometimes it's a winding road to figure out who we are. These are the situations that make life interesting and rewarding despite the hardship. To me, it's worth all the discomfort to be who you really are, to be true to yourself. We can't go back and alter the past, and to deny one's own nature is to live in avoidable suffering. I can't presume to know how difficult it is to be married to someone you're not really into, but honesty and compassion are the two best tools your have at your disposal. If you're honest with yourself and your partner, you have done everything you can.
