Tips on getting over a break up?

It wasn’t really messy , but I’ve been on and off with this guy for almost the past 3 years and I wanna say it’s finally over. I feel as if it’s over, I really don’t wanna go back to the relationship I wasn’t happy in it at all towards the end. But I still love and care about it it’s only been a week basically so I know I’m still healing and stuff. One thing I can say is it was a very clean break up . Until I took it upon myself to just get him off my social media then he kinda just snapped and blocked me, which I think is perfectly fine I honestly forgot about it 😂. I think it’s better for me that way to get over him because he put me through so much shit ! I just need tips on how to handle myself properly, what I’m too expect in the later weeks and months. And honestly how I can deal with it if he gets into a relationship with someone else. I hope I’ve moved on and in a sane place by then but if not I just need tips. I really wanna focus on myself and just love myself again . It really is a nice feeling not having to worry or put someone else as ur first priority ! It’s just been a rough around the edges since this journey began.

So please ladies give me advice or tips but don’t be rude or hateful.

Everything is appreciated xx
