I relapsed

So I have been self harming for 10yrs and recently tried to quit for good I just cut again tonight after not having cut for two months which is the longest I’ve ever gone

I’m afraid my bf is going to break up with me he’s a former cutter as well and he is proud I’ve made it two months it’s new relationship and he’s never seen my cuts before so I’m afraid if he finds out I did and I didn’t call him he’s gonna break up with me
