We broke up and it became too much to be friends and stopped talking. We said we’d move on even though we still liked each other. I still like her a lot. But I’ve started seeing another girl. It’s just casual, but we see each other a lot and it’s amounting to more. My ex had apparently (according to sources) moved on, but I don't know if that’s true. She found out about my new gal and posted songs about the other person moving on and accepting it and stuff... she also posted a video of her reading the book I got her and a pic of the necklace I got her. I posted a pic last night of me and my new girl doing Jell-O shots and then my ex blocked me on Instagram... is she jealous? What’s up?
