What am i doing?

i am so incapable of keeping anyone happy... things change so damn fast and i have become so very slow. Hurt her who i love the most... she cried over lunch today! i just sat and gazed... couldn't say or do anything because i was at fault and there was no denying it. hope this pricks me again and again in the coming days so i am conscious of what i am doing and take care of her happiness. don't know how to change the other factors that hurt her but i can change myself i am sure...
