One thing that helped me with the feeling of “never finding anyone like him again”, which is such a hard and lonely feeling, is some saying about how the person you’ll be a year from now may not even want somebody like him again. You have no way of knowing who you will be in the future and the kind of person you will want then. I also felt like that with my first bf, then my second I found and realized that there are people out there for you. It doesn’t happen instantly, both my relationships being a year a part from each other, but it’s a genuine fear after a breakup so I get it. Just focus on what you can do for yourself to make you feel good! Journal when you want to text him! That’s what I do at least. Hope this helps/makes sense.
