Wood elves (and Halsin is one of them) do not bond with one person, they are culturally polyamorous and it is very bad to express their desire to fit into one partner. Golden and Moon Elves are unlikely to look for partners among Wood Elves, because they know that they have no chance of a lasting relationship. So it's in line with the principles of DnD. Halsin doesn't know the world of lifelong relationships or long-term relationships.
It was debunked in other thread: the polyamory of wood elves was mentioned only once and only in one book which is not even a rulebook. Forgotten Realms wiki is made by fans hence it is not a good source of material, so taking this "fact" from it was a developers' mistake.
