What did she lose? All those years of doing what you call acts against halacha, were years she lost out on zechusim etc…, yes she turned it around, good for her, in fact she gets schar for that.
What did you gain? All those zechusim, I wouldn’t minimize them in the least.
The bigger problem the way I see it, is that your attitude is off. You seem to imply that being straight during your formative years is a means to a goal of getting a wonderful spouse. It is a goal unto itself! I tell my own teenage children, don’t determine your actions based on whether this will get you a good shidduch, determine your course of action based on whether this is ratzon hashem and if it helps you grow in torah and yiras shamayim.
