I agree with your first paragraph, but I don't totally see the second and third the same way. Being a hermit can be temporary, both historically and psychologically — it doesn't have to be a lifelong thing. In that phase someone might not be focused on romance; they could be searching for something else and need solitude. It can also come from feeling alone, like missing someone or not connecting with the person they're with now. That doesn't mean they're permanently withdrawing from social life or never going to be open to romance again. For me, the Hermit has shown up during crises and times I had to step back and figure out a new direction, but I haven't stayed in the cave forever 😉
The Hanged Man, to my mind, is either someone stuck and stagnant or someone deliberately trying to see things from a different angle.
If you're reading the Hermit for how someone feels about a girl, along with the other meanings you've gotten, GraceM, it can point to a kind of loneliness whether she's around or not. Other cards will help give a clearer picture.
