Hello Mike_J,
I am not sure. Personally, I think it's setting myself up for failure if I think about stopping FOREVER...it's way too much pressure! I think that 7 years without cutting is fantastic. I also think that 7 days of not cutting is fantastic. It's all about perspective.
Myself, I take things one day at a time. And each of those days has led to about 8 months now that I haven't self-harmed.

Do I know if I can keep this up the rest of my life? Definitely not! But will I do my very best to get through this day without cutting? Absolutely. And even if I fall off the wagon in the future, what matters isn't the relapse: what matters is that I dust myself off and try again.
