NEED HELP PLZ READ TO START TO END.?

Cindy. you should just move on. your trying to be her family. even know she acting like a child. you said that your mom and dad had you. that means your half sister is way older then what you are. you was a kid your self when your sister had her. she should learn how to forgive. and let go. also i seen where you would buy her things for her wedding ect. stop. because if she cant even say happy brithday to you that means she dont even care. & yes. i dont think its right that you have to go though to get to your own neice. thats rude for her to make you feel like that. &your just trying to make things right. you dont need to talk like that. your neice dont want to try and give you a day in heaven to be her aunt. if you been talking to her 3 years now she should be more then happy that you are trying to be in her family. you do not have to kiss other ppl azzez if your not family to them so thats rude on her behalf. im sorry that your feeling this way.. but look she rude to you. and you dont need that. have a nice day.
