Sounds like me. I had short hair for many, many years. I let it get what I considered long & had it it many longer styles for about 3 years. Last hair cut 2 weeks I finally decided to go back to my short hair. I couldn't be happier.I have super short hair and love it! I would NEVER go back to long. I don't ask anyones "permission" nor do I ask/care about "approval".......my hair is short for ME! If someone else does not like it......too bad!
It's easier to take care of & it looks so much nicer on me. With longer hair every day was a hassle to get my hair to look the way I wanted it to.
I'm not sure my DH was over thrilled that I went back to short, but I did it for myself, not anyone else.
It's naturally wavy but I would say I straighten it about half the time. Sometimes it's a pain to take care of but I don't like the way I look with short hair so... I keep up with it!
It's still long, just below my shoulders and I had major layers added in. 
If everything else has been upgraded to make you look young, odds are the hair will stay long to keep up appearances.
For what it's worth, my hair is longish, but all my parts are original.
