Yearning for whats lost

Recently broke up with someone as I felt that we just had too many things that were different between us, and while i miss her to an extent, I knew that it had to happen.

Thing is, Ive been missing my previous ex a lot more, thinking about her a lot more. Its once Im on my own again, my mind goes back to her. We were together for 4 years, longest relationship ive ever had and we broke up on good terms, wasnt messy or anything. What gets me the most is that I havent spoken to her since. I wish I could talk to her again, just to see what shes been up to u know?

Ive obvsly been trying to get her out of my head, see other people but when I go on dates i just feel nothing. I dont feel that drive to get to know them more or put in effort when it comes to building a relationship with anyone, not just in a romantic sense either.

Its like my previous ex got to know me inside and out and now that thats over, Im not sure I want anyone else to know me like that again.
