Why did guy tell me "thanks love"?

Anonymous
A guy sent me a message on Facebook asking me something (about work). When I told him the answer to what he asked he said "thanks love".

People say he likes me and say he stares at me. He also helps me out a lot, hugs randomly and supposedly I'm one of the only ones he talks to.

I know this is just a term some people use and I always over think things but I've never heard him ever say it before. Usually he just says thank you.

What did he mean by saying "thanks love"? Is he hinting at something?
