I think what influences it is the order in which you do things. I have started the Astarion, Sadowhearth, Lae'Zel and Gale romances at the same time and when I go to sleep after the party I get all four as an option. BUT I didn't agree to start anything with any partner until the night when Gale's weave scene took place.
If you accept a relationship with any other character before that, I think it influences Gale's attitude. Likewise, I never made him wait to give a magic item when he needed, and I took him with me almost all the time, always doing things he liked.
I think the problem is hearing the changes due to all the people's complaints about Gale and now to have a romance with him you have to do a gymkhana.
