Stop hoping and stop dreaming! He really can't be yours! Remember he's already happy... convince yourself girl! He loves her, you know that, very much! They'll be soon Mom and Dad...you can only be friends and nothing more than that!
You can never bring back yesterday where there was still chance for you and him... stop thinking what ifs... because you and him? You're not planned for each other, there's a lot ahead of you... just be patient and you will see!
That's life, you can never always have what you yearn for... if they're not really intended for you, kahit anong pang pray ang gawin mo if they're not yours it can never be yours... it's hurts but it's true!
