I'm so sick of my situation w/ my bf.?

I'm sick of mine & my bf's situation. Been together 9 yrs, have 5 yr & 6 mo old, live in house together, but are not married or even engaged. Our relationship feels more like a roommate arrangement than a bf/gf thing. During my pregnancy my bf slept in our sons room on his bunk bed to help him get used to sleepin n there cuz he used 2 sleep w/ us. Now the baby sleeps n our room. So instead of sleepin in bed w/ me, my bf still sleeps in our sons room. We never kiss or hug. He doesn't pay any attention 2 me. It's just like he's my roommate. I don't want a roommate, I want a bf. I've told him this. He's not a bad guy, he's not a cheat, a beater, or a guy who doesn't hold a steady job. So I have no reason to leave him, he hasn't done anything wrong to me, he just doesn't treat my like I'm his gf. Sometimes I just want to leave, everything is an excuse. But I have no validation to do that. I don't want it to get 2 the point where I've had enough & the love is gone.
