can't get over the 🍆

This is the typical "cant get over my ex" post but I really need advice. My ex and I were literally horrible for each other. Complete opposites not much in common and we just couldn't work out. But the sex 😩😫 The sex was mind blowing every single time. It's like we were soul mates when it came to sex. He's hands down the best I ever had and I can't stop thinking about it even though I need to let him go. He feels the same way and knows we have amazing sex but we just can't keep doing this. I can't find anyone that even compares to him either. What do I do because I really can't let go and it's bugging me 🙄
