Semibisexual

Someone who is attracted to both gender but will only date the opposite gender.

Joe: I think I might have a bit of crush on tom.
Grant: But I thought you're dating Tanya right now? You didn't tell me you were bisexual.
Joe: I'm actually semibisexual. I may have a crush on Tom, but I will still exclusively date women.
