Need bsf advice asap

I’ve always told myself that’d I never be able to do a long distance relationship... my bsf recently moved and I honestly don’t think I can do this for much longer. I’ve gotten to the point of wanting to stop talking to her completely. Idk if this makes any sense but she has been there for me for 11 years and now that I can’t see her hardly ever I don’t want to keep going through this and I’m thinking of trying to stop talking to her completely... what do you think?
