I also have a hard time wrestling with this question. My therapist told me "Don't worry about labels". Yeah! Easy for her to say
This old dinosaur spent a good part of her life playing chameleon. Aside from jocks or other sports 'Enthusiasts' I can blend in. I had no choice but to blend in as a male. And... I done good. I have a very well established male life.
Yet for decades it wasn't 'Me'. I always had this major female aspect of my self that I need to bury. Heaven forbid I slip up and someone figures out I'm "One of Those

". It gets tiring. Eventually the dysphoria wins the battle. Which it did with me
When it did, I knew I needed to figure out how to make those two great aspects of me live happily together inside my body. I knew without a doubt since I was a kid, I should have been a girl. I wasn't, so what's Plan B? I'm now on Plan C, maybe D.
Between my career, which is more like I cannot believe they pay me to have fun; and my life partner, BFF, soul mate and reality therapist, if I fully transition I stand to loose both. But I also need to survive.
I found that if I think "I am Transgender" (I'll show my age, "I am a Transsexual Woman"), the next thing you say to yourself is "Now What?" Well, If I am a TS, it's fully transitioning. At least that is that is what "They" say you need to do.
Over the decades I found low dose HRT to be a lifesaver. Now, with full dose, I find joy living in my body. I have learned after many years of hard work I can actually maybe make it going full time.
Great... except for one minor thing. I may want to, but I don't really need to. Everyone in my group who did needed to. Basically they had 2 choices, transition or die. One had a do-over. Luckily, I am not at that point.
Oh I want to, I think. Yet, there are so many aspects of my "Male" aspect I like and stand a good chance of loosing. Respect for my abilities being the biggest, after a wife that may eventually cannot stay on the roller-coaster.
If I say I am a TS there is an implication the "End Game" is fully transitioning. BUT, If I say I am Non-Binary...... well then I am not 'Expected' to transition. I am "Allowed(?)" to be somewhere on the spectrum between cis-female and cis-male. In fact, I can be both female and male in my presentation.
What never changes for me is how I think or feel about myself. Case in point. Both of my therapist have asked me "What would be different or change if Joanne showed up to work tomorrow". Both times when asked I had the same instant answer "Nothing... other then wearing a skirt", after the dropped jaws and WTF

Years ago I was two different people. After a lot of hard work I am finally one whole healthy and mostly happy person.
Might I be happier if I transition? Not if I loose a lot of other things that make me happy presenting as male. Guaranteed if I "Needed" to, I will as a matter of survival. Today, I can survive better as a male.
Yesterday I was dying inside not being me
