Why?

I'm stuck. Remember my last post, where two guys told me they loved me. One meant it, and Bri IRDK. But now that's coming to get me.
Ok:

• Andrew likes me
• I like Brian
• Brian (I really hope, IDK anymore) likes me

Now Andrew's off using "those three words" (that's what I'll call it) on me again, and now he's asking why my life is so complicated even after I told him main points. Yes, this might be the Summer for Love," but it shouldn't be algebra hard. Help me, I'm so confused right now...
