relationship help.......

Well okayy im gonna try and make a long story short ive been with my boyfriend for 5 months now everythings been fine, no problems. Then my ex from whom i met over the internet texts me and says hes moving down to houston and is breaking up with his girlfriend to be with me. So what you think? Well i still have feeling for him, But I also still have feeling for my boyfriend. I dont know what to do I stilll love my ex but i also still love my boyfriend? I know my ex will treat me right and make me feel like the luckiest girl in the world, but with my boyfriend we never have any problems and rarely have any problems.
