Well, my two cents is that you are fine and wise to change what about yourself you wish and have been trying to change - things that come from the deepest urge to make you more YOU.
Changing to fit somebody ELSE'S expectations - and THEIR version of you (er, ahem - their version of a perfect partner) - that, and the relationship, and you depending on how deep and long to try to "change for somebody else" - are doomed, doomed, *doomed*.
I'd say don't bother. It's the same reason I don't lie during job interviews (been awhile, but I know myself and remember the tug and my will to resist it) - if the job is not right for me AS I am, then - no matter how much you may need work, it is NOT gonna work out.
Same thing with the love of your life. You find that person when you find the person who takes YOU as YOU - and whatever journey and/or changes that come with the package.
