Hey Jen <3 I'm sorry you had to go through all that crap with your ex before you could finally get away from him, and I definitely understand that you still want to feel loved and needed (though not necessarily by a douche like him). He's not the only one out there, though, that can love you; there are better options, believe me. If you're lonely try getting back in touch with your friends and finding new people to hang out with/maybe date. There's no reason for you to go back to him just to feel needed; if you start thinking like that try going over your history with him and how badly you needed to get away but he wouldn't let you. You don't need someone like that controlling you, ever. You made the right decision.
