Ok i'd be telling her far less therefore she asks less questions about your personal business, if she msgs you constantly just ignore them, the more you answer the more she will do it.. *invent a new hobby*, so therefore busy all.the.time.
Joking aside this didn't stop the lady i was friends with tho., it was normal for me to get up to 5-7 msgs in the middle of the night asking if i can go drinking with her tomorrow or the next day or the next. I stood firm and said sorry nope as its my family time. What bout blocking her on FB? She won't see anything bout you or your profile., just say you're closing your account for a bit.
