Let's Talk Hair

Alright so I had this all typed out earlier and it disappeared right before I could post it so I'll try and make this long story short. I have had a love-hate relationship with my hair for as long as I can remember. It's thick and soft but it gets frizzy and it grows funny. I have this picture of myself on my wedding day with long, soft, wispy hair but I have no idea when I'll be getting married. I've wanted to shave my head for a long time but I also want really long hair. I've had a pixie before, multiple times, and I loved the freedom of it. My hair grows relatively quickly. I know that if I do shave my head I can always wear a hat or buy a wig to cover it when I don't like it. My SO has seen me with a pixie almost every time I've had one but doesn't like the idea of me shaving my head even tho I wouldn't be totally bald, I'd leave a little fuzz on my head. I know that, ultimately, I'm the one that has to make this decision and I'm the one that has to live with it until it grows out. All I want from you guys is a little help and advice. What are y'alls opinions and/or experiences? I'll post a couple pics below of my hair now and when I had a pixie.

My hair now^^^

My hair when I had a pixie (this picture is after it had grown out for about a month, the side was originally shaved off with a size 3 guard and the top was a bit shorter, also don't mind my face this picture was taken at like 3 in the morning lol)

I'd also like to say that my head and face are actually not as elongated as my camera makes them out to be lol.
