Why oh why?

why oh why I kept thinking of her this couple of days, remember the girl that I wanna propose to last time? Well, the thing is, this couple of days, I've been thinking that I wanna propose to her again and again, it's not that because i'm like a weirdo that is obsessed with her, just that, everytime I think of her, everytime I smell her scent, everytime thought of her crosses my mind, I would be in cloud nine. My mind is telling me that, eventhough I dint propose to her yet, I still need to tell her somehow I love her and all I want to is being there for her. I don't know what should I do now, if only I had the guts to kneel down, and finish it done.
