Anger management issues. Huge red flag..
To me in translates mostly as she's not over her ex and jumped the gun too soon. She said she likes me and finds me attractive but obviously can't do enough..
The best way to look at that is that, yes, people can change. The leap of faith is yours to take. As long as you can make compromises that you can both live with to move forward, and you feel it's worth it, then there's not much else others can say..
