A friend that I work with set me up with a guy that is 2 years younger than me. We went out and had a great time and during the first date he mentioned that he wanted to take me out again. We got together and I thought we had a great time, but at the end of the second date, we went our separate ways and he has not called or texted me. He seems a little shy to me and I have no clue what to do. I think he's interested in me, should I give it more time?
