Undecided Question

Could someone read and critique this?

This is just a rough draft and I'm looking to improve it

Chapter 1
"You okay Forest?" I asked my boyfriend worriedly.
"Oh yea, just…tired."
"Okay." I gave him a sideways glance. He had been acting strangely lately, sometimes avoiding me, and sometimes almost suffocating me with attention. I did not want to think about what it all meant. Not tonight anyway, on our eighteen month anniversary.
We resumed eating in silence, unusual for us when we sometimes stumbled over our words and interrupted each other in our rush to say something.
The walk back through the parking lot to Forest's ancient little Accord was almost just as silent. I felt so awkward and I was almost squirming in my own skin. This was the first date I was wishing was over early.
"Hey…Sadie, can we talk."
"Sure." I gave a short, fake sounding laugh that made me wince when I heard it. "What do you want to talk about?"

We got in the car and he drove me home in silence. I was trying to pretend the tears leaking out of my eyes weren't there, knowing that they would just confirm what I had feared all along. That I was a pathetic, clingy girlfriend whose boyfriend had no choice but to dump her.
I stumbled up the steps in my heels, slowly unlocking the door, happy that at least my grandparents weren't home yet from their meeting.
I walked like I was in a daze towards my room, ignoring the bed and throwing myself down on my beanbag, sobbing. After my loud pity party was over I walked over to the bathroom and looked in the mirror.
Swollen eyes that weren't a spectacular color even when they didn't have red in them – muddy brown, really. Pale, splotchy face, body nothing to brag about, too tall and awkwardly big in the wrong places, my hair was all right, long and naturally straight, a deep dark red color, but who cared? Forest had rejected me, and I was drowning.
He had first befriended me when I had m
