When a man asks for space, is it over?

we've been dating for 2.5 years, we both expected to tie the knot. During our 1.5th year, I noticed he can't manage stress at work and our relationship at the same time. however, we worked things thru. When our 2nd year approached, he got a new female BOSS who drills him, our relationship SOURS. He asked for space as he finds me burden but I can't accept. He stops calling, replying sms and talks rudely sometimes. 3 hours ago, we broke up. He said I'm very annoying & proved me wrong that I can't give him space he needed. ANy chance we can patch things if I really change and NEVER call him unless he calls?
