If you're just going to be a dickhead, why bother posting at all? Perhaps I should intrude on your threads, presume to understand your motives better than you do, and then resort to snide comments when you ask for a reasonable explanation. That sounds like fun!
I'd like to know why it's so clear that my relationship is centered around competition with my friends.
You've been given good, if brutally honest advice from multiple people. The majority who have concurred that this is a relationship best consigned to history, all based on the narrative that you have chosen to share.
In response, I've read multiple defensive attempts to rationalize your rejection of the advice to stop the relationship, which ranged from guilt about what would happen to her if you left, to quoting poetry that talks about how 'love' requires a great deal of emotional suffering, to trying to convince us that your situation is relatively normal, and that it's worse for some of your friends.
It's that last justification that prompted my last post. I'm not saying you're making it a competition. I'm saying that you've realized that you're a lot more emotionally invested in the relationship than you were thinking at the time you wrote the OP (done in a fit of frustration, as you've admitted), and you're finding reasons consciously or subconsciously to stay in it. One such is to convince yourself that dealing with a girl that throws emotional bullshit at you is normal - and that in fact it's not so bad because, hey, you're at least having sex while some of your buddies are even getting cut off.
I'm even going to go out on a limb and say that I bet you didn't think people would be so strongly in favor of you leaving the relationship, that you expected a few women at least to say it's normal and to be reassuring - to give your investment in this girl some kind of validation or approval.
Maybe I am a dick for putting that kind of thought and analysis into what you are saying, but hey, you're the one that aired his laundry and asked the forum's opinion. If I make a thread soliciting peoples opinions, feel free to be as brutally honest as you want. I'd expect nothing less.
