Tired

Have you ever loved someone so much that you had too much expectation on them? I have and I'm in the process of it. I've dated him for 9 months -no, it's almost 10 months- and lately I got sngry easily for something unimportant. It's not like it's unimportant at all, but I always got angry for small things. I always thought he is the one who always got wrong. Ah I just couldn't describe how I feel...
