what am I supposed to do?

I'm just so confused and unsure. It was just like yesterday when I was so sure and now I'm having doubts... or maybe it's more of confusion.
It was just yesterday when I was so in love but now I don't know. I still love him but does he really love me? I really don't know. Maybe it's just me who is having this kind of feeling.
But I know that I still love him because he is all the I can think of. Thinking of him makes me smile and makes me feel loved. It's just so hard. Maybe I'll never understand it.
What am I supposed to do?
Does he really love me? Does he mean it when he says I love you? Does he also think of me?
Why is love so complicated?
I wish I know how he really feels for me. I wish I know if he really loves me or not so that I can just move on and to start something anew.
Why is true love so hard to find?
When can I find my true love?
Is he also looking for me?
