CG: it's not about that at all....the key to the previous posts is relying on your partner for your happiness and giving up making yourself happy to do that. That is the pure definitioin of co-dependency. See, the thing is, if you rely on someone else for your happiness, you also will blame them when you're pissed off, horny, frigid, cold, warm, etc.
The thing the comments in this thread don't even touch on, is that a relationship is made up of 1 + 1 = 2. ONE plus ONE. Two distinct and unique individuals. If you lose that, you lose the relationship. EOS.
Using you as an example, and using Amy's "spend your life making your partner happy" you'd have to give up biking because, other than getting you out of her hair for a while lol, how does that make your wife happy? She's probably happy you do something you enjoy, get it? Something YOU enjoy. I know you'd probably like it if your wife took up the sport, but in Amy's definition, she should. She should do that because it would make you happy(ier). But in the meantime, she'd probably be miserable otherwise she would have done it by now.
I've used this example before: I dated a girl and one night at her place she was making Kraft Dinner. SHe said she puts dried mustard in it, try it. I tried it, hated it (tasted like ass) but finished up. So a while later she's making it again and I ask her to scoop mine out before putting the mustard in. What'd she do? Put it in without taking mine out....when I took a bite I said "you didn't scoop mine out"? Her answer? No, you should learn to like it because that's how I make it".
Sorry, but it tasted like ass and by the definitions put forth here, I should eat it even though it made me naseous "just because it made her happy". Sorry, that is the purest form of co-dependency. I will not do something detrimental to my health and happiness just for the sake of someone else's happiness.
Put it another way, would you FORCE your wife to have a threesome if she didn't like women? Sooner or later she'd start to resent you. By the definitions here, if a husband, wife, boyfriend, girlfriend, wants their partner to have a bi-sexual experience, they should "just because it made their partner happy".
So, if your wife CG asked you to let a guy fuck you up the ass, would you? (just to make her happy)......I bet you wouldn't.
Now don't get me wrong, I'm not talking about sharing housework, picking up after yourself, or what would generally be called "maintenance" stuff. Stuff like seeing her parents if you really didn't like them. I'm talking about things that are "you" at your core (in your case biking) or things like letting a guy push in your stool for you. I'm talking about say you wanting to buy a Blu Ray player and her saying no because she wanted a new pair of Jimmy Choo strappy sandals......
I can't TELL you how many times I've talked to guys and women who have said "oh I can't do that without checking with _____ first" (when discussing things like buying something, or making a date to go watch the UFC or ??). Sorry, but if you have to check with your wife to see if it's ok for you to go out, it's time to have a big long talk with her and it isn't about you going out. I even heard someone say "they might have made plans" well BFD if they did? If they did and didn't tell you, then it's their fault.
See I see a relationship as a partnership. She has her life, likes, loves, habits, hobbies, etc and I have mine. We can do our own thing apart, we can do things together, and when we do things apart we come back and share our experiences with each other. A great couple I used to know used to do things apart all the time. She was really into fencing and (I forget what he liked to do). When I talked to her she said "oh I love it when he goes to ____, I have the place to myself for a few hours and he comes home happy". He said "oh I love it when she goes to fencing, I have the place to myself for a couple of hours and when she comes home all charged up she fucks my brains out".
