Right there with you...
This stuff is hard, and it hurts. I've made mistakes (plenty!) about who to share my life with, and love with. But crying is a good thing (even when it doesn't feel that way). It is early days for you yet from the end of this relationship, and you need to heal.
May be wise to stop contact with him for now - only you can know if that's something you can do, and if or when it'll be good for you to re-initiate any contact. I've found that with some people, it is far better for my own well-being to just let them go. There's a difference between pain and torment, and I'd chose good, clean pain, any day. To get to that, I've had to step out of the ring.
I've found this gives me space to focus on my own recovery, sort out the scramble in my head, and invest my energy in the person who most needs my love right now - me!
Wish you well
