I have a crush on a guy and he kinda likes me back too but he never ever ever stops talking about his ex. It's all he ever talks about and brings up.  He claims that he is over her and that he would never go back there again or anything like that but he never shuts up about her. The split like 4/5 months ago.  I really like him but every time we talk he mentions his ex more than anything, bring everything back to his ex.
