betrayed by my bestfriend

Why?
I was doing fine before you came back. I'm living my life the way I wanted. Though I frequently pray for "him" to come my way still I was pretty happy with what I've had. Then you came out of nowhere, after 10 years we met again. I was happy, excited and overwhelmed. I never thought we would see each other after so long. But, hey! it happened. Then we moved on to the next level of our relationship. We tagged each other as boyfriend-girlfriend. At first I can't believe it's true. I've never had anything that fast. But, I just let it be since I've known you for so long time (as I thought). I enjoyed the road trips, night hang outs with some of our friends, out of town, swimming and just being with you. I believed everything you said about yourself and your family. But secrets are meant to be revealed. Lies were unveiled. Slowly I'm figuring out what you were hiding. Though I don't go searching for it. I accepted some of it believing it was just a few. As days go by new things are coming up. You are like a puzzle for me. I'm waiting for your revelations but it seemed you want to conceal it. Now, I don't know what to do, what to believe and if I would trust everything that you say.
