I want to go out with this girl but don't know what to do?

[Brogan]

I really like this girl, but I don't know how to make move on her. We talk quite a bit and get along well. If she did a 'like for words' thing on Facebook shed say I'm a lovely person, easy to talk to, good music taste, etc. She also says I should hang out with her group of friends, since we don't hang out that often. She's also offered to dye my hair this summer, also told me to say to my family that she loves them after I made a remark about them (I find that odd, really).
I really like her, but don't know how to make a move because she often has boyfriends and all that. What can I do?
