I really have no problem with it but it's just kind of confusing... I don't understand. He said he still loves me but I'm sooo confused. Help?

What exactly are you confused about? The fact that he's bi-sexual and said that he loves you or the fact that he has a girlfriend and he said that he loves you?

Sorry if the tone seemed a little snobbish, just wondering what you're confused about (your question seemed unclear to me).
