in love for long

SO me and my g/f broke up about 4 days ago and she has been treating me like shit ever since then and i dont know what to do Plus to add to it im falling for my ex again and its not a rebound ive always had feelings for her they are just so much more now and i don't know if she is flirting with me i mean it seems like it but then again i don't really know can some one tell me if i should talk to her about it or if i should let her come to me. What do you guys think.

why did you and your ex break up for in the first place?

Firstly let me get this straight….

Your girlfriend and you broke up for four days now
She has been treating you like shit until now
You are falling for her
And she is flirting with you?

Ok from what I can salvage from what you said. I can say that your ex-girlfriend that you dumped is treating you like shit, because she still has feelings for you, but the only way to release it is through bullying.
