The only people I know personally who tried to detransition had very deep regrets. My one friend stepped back three times before finally breaking through, and she deeply regrets ever detransitioning in the first place -- she could have had her proper life in her early twenties rather than suffering into her mid-forties. The other tried to go back when she fell in love with a bombshell, but of course she ended up getting more and more dysphoric, and she too couldn't hold back any longer.
It's a myth, I think, that dysphoria can be happily managed or suppressed long-term. The truth of who we are will win out, one way or another.
That said, I do think it really depends on your truth. If you're not actually dysphoric at being misgendered, for example, and you get into transition and realize it's really not any better than before, then of course it makes sense to go back. If you're not on the gender binary, or you find you're quite a bit of both, it can make sense to pull back. I even think it makes sense for practical material reasons -- like, if you know you're not going to get gendered in the way you want, and you think you should capitalize on your financial growth while the getting is good, okay, in this day and age of the unstable global economy, why not.
I think what really bugs me, though, is the idea of being emotionally manipulated into not being your true self. That, to me, just seems so dishonest, and so full of unhappiness. It's hard enough dealing with gender dysphoria in the first place without having the cudgel of emotional blackmail hanging over one's head.
But even if I think it's a mistake, even if I've argued otherwise, I'll still support the choices of my friends in the end.
