You don't need anyone in your life who don't care about your feelings or won't help you when they know you need them. The best thing to do is remove them out of your life. You don't have to tell them why either. It's pretty sad how some people only care about themselves.. You always try to help them out but when you need them they leave so it's okay to remove people like that out of your life. Don't ever feel bad for letting them go! You deserve someone or people so much better than that!
