My relationship ended a few months ago because neither of us were mentally in a place where we could be with each other without hurting each other. It’s been long enough that I feel like I should be ready to start dating again, but i feel worse after going on dates and just thinking about having sex with someone else makes me sad. I don’t know how to move on from someone who I planned a life with and who I still love deeply. How do you work through heartbreak?
