Should I??

I’ll make this short. My bf (maybe now ex) and I got into a very serious argument. He hasn’t contacted me for 6 days! Yea call me stupid .... I guess inside of me wants him to come back.

Some guys friends told me to give it a week because guys sometimes need a lot of space to vent 😑

In my head I feel like it is the end but idk if I should shoot him a text so he can really give me that closure over text. Something like “sorry but we need to leave this relationship behind. It’s not working out” Sorry don’t judge me. We have been together for 5 years .....and no we never lived with each-other due to financial issues

This happened just so out of the blue. I hate ending any type of relationship like this.
