[Roses Are Red]

Please help me interpret this dream.

I had a dream that I was at a convention and I see my ex and he is just looking at me from afar, no smile.

I move my eyes and see a women standing 5 feet from him, looking at me and I tell myself is that his new gf? she looked weird had medium straight dark hair and bangs and was sporting a blue sweater.

Then in my dream I turn my back and go about having my own fun with my friends :)
* In real life I dont know if my ex has a new gf.

Can someone interpret this dream, who is that women? if they are dating, they looked dull and were standing pretty far away from one another in a crowded place.

Please help !
