bf issues

So my boyfriend and I have been together for nearly 2 years. He just recently told me "in general I don't want kids or marriage" I'm so heartbroken and devasted and extremely depressed about it. He knows both of those are super important to me and I feel so lost. I love him so much and am so emotionally bonded to him that I am scared to leave. I feel like I won't find anyone like him and I wanted these things with him but I guess they won't happen... what do I do?
