He said he can't trust me. What can I do, do I give him space or prove myself...if so how?

He says he doesn’t trust me anymore and says it’s the last time (because I talked to a guy friend of mine who im just friends with but he didn’t like him so I lied about it and it hurt him) I love him deeply and he is my soulmate and I know he loves me but says he just can’t risk getting hurt by me again. Can’t stop crying:-(
