Why do I feel like I need him?

Don't worry so much every girl goes through the whole she thinks she needs him. If you are really attracted to him not in a lust type then maybe you are good together. Feeling insecure about it is also a part of it. If he can not see his own feelings and treats you bad then it is better to try and get over him. Although I am probably not the best to give advice since I just got out of a relationship myself. Although eventually I keep telling myself I will get over it and I will. So I guess the best thing to do is if you want to be with him then you should try and if you think you want to be with him but are afraid then well maybe not. Although it is better to try and look at everything and not limit yourself.
