text: you need to tell him that you are not ready to be in a serious relationship yet, because obviously you arent. you need to take some serious time to get over your ex, or if you want to try to go after you ex again do that too. but you are obviously not ready to be dating anyone else yet so you need to tell him that and let him down gently. if you dont break up with him things are only going to get worse because he will just get more and more attached. dont feel too guilty, you really cant help the way you feel. the best thing you can do is let him know you care but the timing is just not right.
