I was married to a woman who took the other fork in the road, Dunollie. She thought she was bi, but she just hadn't met the "right guy" yet. After we'd been buds for a few years (during which she had relationships with several women — I was that friend who sat on the couch with her while we passed the ice cream back & forth while watching silly movies after a breakup) we got married... and she realized that nope, even with a guy she loved, she just didn't get enough out of sex with a man. She embraced being a lesbian, she's a VP at a college in the south, and she's married to a wonderful woman and not afraid to let everyone know about it.
Good for you for putting your story out there!
