Boyfriend of 2 years dumps me after mention of marriage

I've been dating my boyfriend for 2 years. We've been friends for almost 5 years so we know each other pretty well (or at least I thought). We moved in together a year ago (mostly because I pushed it). About 6 months ago I wanted a dog. Again, I pushed it. In many ways, my boyfriend has come around to this whole idea of us as a family (me, him, and the dog) - but I still feel resistance. He's quiet and doesn't talk about his emotions much. What's difficult is he wanted to be with me so bad in the beginning of our relationship. I (on the other hand) was more or less happy single but def open to finding a long-term mate. He wasn't my dream guy - but the more time we spent together, the more I felt attached. Now I'm a dedicated girlfriend, I don't go out a lot and I spend most of my time home (cleaning, cooking, and taking care of the dog).

I've noticed in the past year or two that I will drink too much from time to time and when I do all my emotions pour out and it overwhelms him. He gets frustrated, ignores me for a few days and then we kind of go back to normal. I mentioned marriage and about a week after I brought it up - he dumped me. He says he's not ready (at 33 yrs old) to commit and he doesn't see a future with me and he needs to find himself. I feel like I've given so much to this relationship and he bailing like a young lost boy. I know I was always in the driver seat but that's because I feel like most of the time he can't make a single decision. Even simple things - what to do for the weekend or what to eat. So I just take over.

Now I'm "dumped" and we spend each day in silence walking around the house (because we still live together). He keeps saying this is for the best but I noticed he's not taking any action to find a new apartment or move out. I can sense he is angry with me (he will make snide comments when he comes home, telling me where to watch TV and that I need to "stay away from him" and he "doesn't want to talk).

I've expressed I love him and I want to help him in any way I can to "find himself". I'm willing to put marriage on hold (I'm not interested in a big ring or party) it just felt like something my heart was leaning towards and that's why I mentioned it. I can wait, but my question is should I? OR should I just pack a bag, grab the dog and go? I'm living in this strange limbo - nothing is happening. Do I wait for him to leave? Do I stay and hope we can work it out?

I'm 31 and although this relationship hasn't been perfect, he's become a big focus in my world. I still work full-time, I started my own side business and I absolutely love my friends and dog. I know I'm not dependent on him but he's my buddy, my guy. How do I suddenly go on without him in my life?

I tried to ask him directly what he's seeking to achieve and all he says is he wants to make "more money" and get out of the corporate world. I don't see why he needs to throw away our entire relationship to achieve that? He was unemployed for 4 months last year (finding himself) but nothing changed. Now he's working and miserable all over again at his new job (the 3rd job in a 2 year period). I don't know what to do. Should I just leave? Or Stay?
