My dream last night

I had a dream that me, a "friend," and some other mutual friends were hanging out at a place that I just knew was "my place,", but it looked like my "friend's" place. Then, in comes my "friend's" ex...and I got so upset! I took her outside and told her she can't just come to my place and intrude like that, that if she wanted to be invited, she should have attempted to talk to me before just appearing, etc. Anyway right before I was about to tell her that since she's here, I guess she could come in, my "friend" comes out of the house and puts his arm around her and starts to walk her towards her car. I get so upset because I think he's going to leave with her and I turn around to walk back into the house. By the time I reached my doorway, I realized that my "friend" was already back in the house, because he is at the doorway waving bye in my direction. Since I think he's waving bye to me, I wave back to him. And then he tells me, no, I'm not waving bye to you, I'm saying bye to my ex...
Okay guys...what do you think?!!
A little background: My "friend" is really my friend...who I had serious feelings for a few years ago...and who I think began to have feelings for me, too...except for the fact that he's in what he calls a "hopeless love affair"...he's still in love with his crazy ex...but we are truly friends...except for the fact, that we've been spending a lot of time with each other recently...and I am afraid that my feelings are being revitalized...
