Perhaps to a point. But, some detractors' theories to the contrary, mages are human. Even those who scrupulously avoid romantic partners will have friends. Mentors, protegees. People they care about. Unless one intends to stick to a solitary mage per tower, I don't see a way to avoid the potential for emotionally intense relationships, even if there's no sexual component at all. It's a danger one has to cope with regardless.

That said, you're not wrong about the potential for separation. But it was one of the practical concerns I meant. Not to mention the potential for awkwardness when things end and the two of you aren't separated.
