Does she actually like me? what is the exact nature of her jealousy?

[Anonymous]

she seems offly jealous when i spend time with another girl at her work ( a restaurant ) like extremely jealous so obvious you can see it a mile away but whats weird is i've known her for years and we've never really done anything partly cause she's had a long time boyfriend or acted uninterested in doing things with me

so left confused as to the nature of her jealousy , is it cause she likes me romantically and deep down does want to be with me or more of a friendship jealously annoyed i'd rather spend time with the other girl and talk to her at her work

but defintly something going on her , just the way she acts is so obvious

She definitely has something for you, if she's showing this jealousy through body language, expressions... it's something serious.

i know seems like there is something going on deep down that she's dealing with towards me which is odd as we've never been intimately involved but have known each other for a long time. perhaps can't deal with the though of me with someone else despite the fact she's been with someone else most of this time
