No. Never feeling lonely is the benefit one gets when they're unable to form bonds. That other stuff is the consequences.

You've already described feelings of loneliness. You stated that you wanted a space for self-expression where you could feel validated and recognized. You're not merely seeking a playmate to alleviate boredom, but a meaningful connection and a sense of belonging. And when you were denied this, you felt saddened. That's exactly what loneliness is.

You may never feel alone, but your lover can't give you validation or recognition.
