If a girl you liked in work and thought might be interested was organising a little group get together in work and invited you along, would you take this as just friendly or would you kinda know she was trying to make a subtle move?
I don't want to be too in your face by calling him up or asking him out, but I want to show him I like him. I don't get to see him that much so I don't get to flirt with him much etc.
I think it would depend on how things had gone prior to her asking me to the get together that you are having. If you were flirting with me or letting me know in some way that you liked me prior to that, I would probably continue thinking you liked me. On the other hand, if you had really given me no indication that you were interested in any way, or if I missed any clues you had tried to give me, I would only think that you were just being friendly. Something to remember is that when you work with someone or are in a group situation with them, if you invite a bunch of other people to a gathering as well as the person you like and haven't truly let the person know that you like them, the person is just going to feel like part of the group. This is ok. At least he knows that you like him as a friend and are inviting him to the get together. When you are at the group, you can show him you like him by hanging out with him and talking to him, etc. Personally, I think you are playing things very well at this time, since you are not wanting to be too pushy or forward with him. Just make sure to take advantage of any chances you get to hang out with him and show him that you like him. Laugh and joke around with him. Find something in common and talk about it. Allow things to progress naturally. You may end up with his phone number or he may ask for yours or something.
From what you say that it's a "little group get together in work" . so I would take it for what it is, a group get together in work" and if I liked you, perhaps a chance to get to know you more :).
If you want to show him you like him, then give him some indicators of interests,[don't flirt until he's shown you he's interested in you]. Don't give too much but just a bit to bait him in. A small harmless comment on what he's wearing, smile at him but then also smile at other guys, if he comes and speak with you, make eye to eye contact. etc. just enough to give him an indication that you might be interested, and hope he takes the bait. Good luck.
