Where's my life going?

me and my boyfriend have been together 4years/ and also have a daughter,
But I'm not sure where we're going, I see everyone else getting engaged, moving in with each other, yet every time I mention it too him he goes distant and won't want to talk about it, or says moving in together, getting engaged doesn't prove anything or that we love each other. 
We hardly see each other at all, when we do hes always on he's phone, texting mates and anytime he gets after work, he would rather go round he's mates or the pub. I'm not sure where I fit into this. Is he scared of commitment.
