So recently we were at an event... I’d had a couple drinks so was a little flirty and was chatting to the brother of my best friend. We’ve had a great relationship over the years so nothing was different. However over the past couple weeks we have been talking more and a few people have said we have great chemistry. I have no idea what to do...? Do I speak to her? Do I go for it and tell her when things are more secure? HELP?!
