OP

Also the plot thickens a little bit. There's a girl I've been hanging out with a lot and long story short she recently became my girlfriend. I have no intention of cheating on her with either gender, but I'd like her to at least know that I'm bi. I understand about her being worried I'll leave her or cheat on her, but seriously she'll probably find out anyway and I think it's just something she should know if we're going to have trust in the relationship.

Should I tell her now, later, what? I don't want her to find out on her own, that just feels dishonest somehow.
