One of my friends, a girl, went through the breakup of a serious relationship about 6/7 months ago. I, along with my friends have been supporting her. Recently though, she started to get very flirty with me. It started with some flirty text messages after a night out, then lots of contact over the Christmas break and the flirting has carried on. When I've tried to talk to her properly about what's going on, she doesn't respond. I asked her if she wanted to go out for a drink to chat about it, but she hasn't responded! I do like this girl, in fact I think she's great but she is also a very close friend and I'm not really sure what to do next. I thought maybe I should do nothing and if she really is interested, things will develop over time?
What do you think?
