sagittarius men when they are interested

How do they act when they are interested? I work with this guy in a different part of company, in the span of 8 months hes told me one story, any other time hes really either really flirty or weird or mumbles under his breath. Is that normal or is he just weird?

We'll pursue if we're interested. We'll hang around you and flirt and ask you out. Him mumbling is weird though lol

so ulalume, if they do all that but then never make a move - what do you think about that?

hmmm, that's what i'm afraid of...don't want to hijack this thread. would you mind taking a look at my sit and let me know what you think?
