Please help me out!!!

Me and my bf are going through a rough patch that I’m not 100% sure we’ll make it out of. We got into an argument and things were said that came across wrong and I’ve hurt his feelings and I feel so so guilty. I never meant to hurt him but I did and I feel horrible, of course I’ve told him all this. He said he needs time to think and that he’s confused about things and doesn’t know what he wants and I’m so terrified of losing him, I’ve been balling my eyes out. Is there anything that I can do to get this off my mind until he’s ready to talk???
