has it gotten better by texting your ex?

so i been urging to text my ex , but my brain and my friends like said dont text her dont go back to her remember how she treated you and all

s o i have had only one relationship in my life till now and we both had an block unblock typshi and yeah i was the one who mostly blocks her cause we had a toxic relationship, even though it was a toxic relationship my heart still thinks of what we could have been ? like the starting phase and fixing all those things and all

and yeah i wanna hear your experiences has it gotten better??
