That makes perfect sense to me and what I would expect. There is no good relating in any area of life without solid, healthy boundaries, I think. For me personally, that does not sting, it makes me feel satisfied in any relationship. The last sentence is key though IMO - the parties involved do need to have a good sense of where one ends and the other begins. The desire for merging and accepted whatever that many people have might be what causes a misinterpretation of what "relational" means, but in therapy way too many Ts make it a mess as well.
