Hello ladies! I was wondering if I could get some advice? 

Sorry in advance for the length. 

So ...(a little background first) about 4ish years ago my boyfriend (of three years) that I thought I would marry broke up with me and I was heart broken. Since then, I have been busy working, going to school full time, enjoying life with family and friends, and just working on myself. My life is amazing and I have grown up so much in the past few years! I haven't really been interested in anybody ...until now and I feel like I'm so out of practice I think I am needing some assistance! 

So..I met a guy at a wedding about a year ago and we were pretty flirty, but nothing happened. So a few weeks ago I was with my friend and her husband, which is this guy's brother, and we were talking about guys he could set me up with...and his brother came up, he said that I would be good for him because his brother keeps dating immature girls and I would be a good switch from that..so I said okay talk to him for me! (I have no idea if he did or not) This past weekend my friend, her husband, his brother (the cutie), me, and a bunch of other friends were hanging out at a barbecue and had a blast! The guy and I were a little flirty again, like last time and very playful..but nothing too crazy because his brother told me that he has a girl he talking to (that things aren't going well with at home) back home and I didn't want to disrespect that. (When I say flirty I just mean joking and laughing together...I promise I didn't cross the line!)  So my friend and her husband are moving far away and this guy lives about 2 hours away......

It's been so long since have had a crush I feel like a little school girl 🙈

SO I am wondering how I should go about this...He is used to girls kind of throwing themselves at him so I don't want to do that but I somehow want to be classy and get his attention. I'm just not sure how to go about this. Please help me!!  

Thank you in advance!
