<human>: I've been together with my SO for 9 months. He decided he loved me very early on, like 2 weeks in, I agreed in a whirlwind. The relationship moved very quickly, we're living together now in a year long lease and he's driving me up a wall. I don't know what to do.

A little background, he's the ex of my ex, a still good friend of mine so that was kind of awkward and my family loves him in part because I'm no longer with a girl. I love him. I'm 99% sure I love him. But the thought of just running away creeps in sometimes.

 He talks marriage and kids and dogs and proposing within the year and I'm just so skittish about it now. I never used to be, so this is definitely my bad in encouraging this but I'm getting the coldest of feet. I never planned for my life to be how he wants it, I kinda wanted to travel and live alone in the city for a bit but now I'm already stuck in a domestic role at 20. My own parents divorced and his are just godawful to be around, terrible relationship but too religious to divorce. I'm afraid of tying myself to him, to a life I don't know if I want, to in-laws I don't like... 

He gets so upset whenever I say I don't really want kids so I bent that for him. He cries when I get angry or frustrated or want to slow things and says he doesn't understand what's wrong, it's like my feelings are instantly invalidated in any conflict by his tears. I don't know what to do. I don't want to leave but sometimes I want to leave everyone.

This first came to a sharp realization when a friend of mine asked how long I thought we'd be together and I said at least another year -because of the lease. I never thought it could get so mercenary and I need advice.

How do I fix this? Do I fix this? If I can't even figure out me how can I figure out us? How can I give him what he wants if I don't even know if I want to be there?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I don't want to leave, I don't want things like this. On different pages, too scared to commit to the wrong thing, too scared to hurt him by refusing. Help?
