I’m confused idk what to do

I’ve been in this on and off again relationship with my ex and it has impacted my life in a good and bad way I felt it was toxic but I’ve been missing him for some weeks now and it has happened before but when we get back together something always happens and we both lose it.it has affected my emotions,and my mood throughout my day I overthink things and cry a lot thinking about everything that has happened to me and also the family conflicts are getting to me I need advice as to whether to text him and ask him if his ready for our love again I don’t know if I should let him go or what.We both have impacted our lives with so much good and bad but last time I felt like it was two toxic and I let him go I told him we need to work on ourselves and I thought he'd text but he hasnt and I have the urge to text him coz I wanna move on if he isn't interested anymore what should I do
