Stun:) Talk to her, tell her your feeling before blowing up on her {Not saying you will, I just know I use to do that no matter what and trust me, not fun}. I've been in the same situation before and I talked to that friend but she's one of those people who have to have her way all the time so she wouldn't quit it. I suggest what I did, shopping around but come back once and awhile to flirt with him agian. It worked for me, I found the guy of my dreams and we're are happily dating.
Moon:) I defininently know that confused feeling. It sounds like you two had a pretty good relationship up to a point. Depending on the issue that broke you two up, you guys will have to work it out. But, if he can't make up his mind for a long while, you may want to seek other options. I mean, I've done this where I've wasted my time on {It kind of sounds like this guy is} a tease but, I totally regret it. It'll be like a train stuck at one station, it has no idea what different, new or old, p*censored*engers await at the next.
Well, I hope I helped, if not lemme' know. :3
