Actual short guy (5'6) weighing in here.
It's been my experience and observation that height is the most important thing to ALL women, by far (yes, I said all and I mean all). If it wasn't the most important thing, then you'd see many couples walking around where the female is taller than the male. I don't know about others here, but I rarely see that. In many situations, a good personality, a lot of money, and looks cannot fully compensate for lack of height.
I still do okay with women, but it's an uphill battle (akin to a DO getting into derm....doable, but you have to put in more work than the MD).
With that said, it's not so bad. Marriage is crap these days anyway. To me, it's definitely not worth having my legs broken, not mention all of the possible complications that go with such a procedure, just to gain a few inches (and I'm legitimately short, not average like yourself).
To each their own though....
