I met a guy about a month ago. We've gone out 6 or 7 times and always had an awesome time. Lots of texts and long phone calls, intense kissing but no sex yet. He told his family about me, introduced me to some friends. Then I went out of town last weekend. Since I've been back I've barely heard from him. He said he wasn't feeling well on Tuesday and didn't respond to my text on Thursday. What's going on? Do I text him again?
