A word of support for those feeling down
I wanted to put things in a bit of perspective here and maybe help some lurkers feel more confident.
No one has it truly figured out. All of us are trying to survive and have one aspect or another of the relationship that isn't pretty or exactly what we'd expect. There's no relationship in the history of this planet that hasn't had difficulties in one way or another - and in that way all of us are in this together.
Just because someone asks for help and the typical comments are something like, 'well we don't have that problem, I do this' or even 'I haven't experienced that, you should xyz' - that doesn't mean you're failing. All it means is that the few people who chose to say something aren't struggling with that particular issue.
I believe a lot of the type-A personality traits have either rubbed off on us, or we're even type-A ourselves because it's a good match. A lot of the comments on this sub are basically proving that it IS possible, don't lose hope, but it's presented in a very straightforward way without a candy coating.
None of this means you're not up to snuff, or that your particular relationship is so much worse than others. It's just a few people trying to support you in a very straightforward way. Remember, no one on the planet is ever perfect and that means it's okay if your life doesn't mirror someone else's.
