Are you talking about the part where I pointed out that he didn't say "Vhenan" during that quest? 
That wasn't what I was implying if that's the case, I was just pointing out he didn't call the spirit Vhenan. Also the Wisdom spirit isn't a girl, it's an it, Solas says so himself.
Though while we are on the subject (and yes I have heard his banter with Blackwall before it's pointed out to me) imho I do doubt Solas would get into romantic type relationships with spirits, I would think that it might risk corrupting them tbh. I won't say it's impossible though, nor am I gonna suffer if anyone ships it, everyone is allowed their own opinion on it.
Though I'm sure Solas has had past relationships, he's too smooth not to have had some experience before Lavellan. Besides, he even says "It has been some time" after the first kiss, seems to suggest he has had romantic involvement with others in the past (we just don't who).
If you read, I refer the spirits as an it in the past.
BUT I SHIP IT! SOLAS X WISDOM!
Doesn't have to be a present relationship, but an ex-itfriend!
too lazy to find it but I also referred the spirit as an it when I was making up my Solas-sucks-at-pimping-out-his-exs story.
