Why can't you be friends with your ex?

My ex girlfriend broke up with me 2 months ago. She said she loved me too much and that she couldnt handle it right now. So she started dating another dude. I tried to wait for her but she even told me to date other women so I ended up getting back together with the girl I was with before I met her





My ex was kind of mad about that but really couldn't say anything because she was with another man. We decided that we would be friends and for the past two months we were





During those 2 months my current GF had family problems and was unable to see me for almost a month. I guess that made it easier on my ex to move on





Anyway today I saw my GF for the first time in a month and my ex found out about it. She went off and told me we couldnt be friends anymore





How is it fair for her to have a boyfriend that she sees almost every night, and its not ok for me to have a GF that I have rarely seen





This really sucks. I've tried to be nice to my ex and now she pulls this. I dont get itWhy can't you be friends with your ex?
She's jealous. Don't let it get to you. See who you want.
