Confused

I can't explain the way I feel Sometimes I can't believe it's real When we are together I'm on cloud nine But when we're apart you walk the line I pretend I dont' see all the things you do But how can you like her and like me too? I've waited so long for that magical day When you'd describe feelings you had held at bay So why now do you take the chance To try and have some "risky" romance? When all along you've had my heart Yet you only want it when we're forced apart Now I have one single question for you I think I know the answer, but tell me if it's true Why do you fill me with all the hapiness I can take Just to leave me alone with a bad heartbreak?
