Can I get Disfellowshipped for dating?

Technically, I am Jehovah's Witness. I've been DFed twice. I'm reinstated but "inactive" because I haven't been in service or to a meeting since April 08. I have a boyfriend. We are not doing anything that would be considered immoral. But my mom told me I would be disfellowshipped again if I continued to date him or if we got married. Is that true?
