My younger sister and I weren't close growing up. My parents divorced when i was in my teens and my mother forced me to watch my sister so she always came a long with me and my friends to Disnleyland, parks, coffee shops etc. As we got older we grew really close and once she hit her mid teens and me my early twenties all of a sudden my mother wouldn't let us do things anymore telling us I am too much older and we should have different friends. I figured she just meant my sister should have some friends her own age so I did my own thing, moved out and such and she did hers. She is 20 now but still lives at home and is going to college while I am 26 on my own. My sister has really gotten into her party friends lately and I had a talk with her the other night about how she can't make plans with me and not show or blow me off and my mom caught wind of the talk. she calls and freaks out on me. Tells me I shouldn't be hanging out with her anyway because of the age gap being such a big deal and she wont let my sister go out with me. Not dinner or movies or anything. I feel like I am going crazy and my sister doesn't get it either. Are we just too far in age to be doing things together or is my mom just kind of crazy? Any advice on what I should do would be great. I have talked ot her and she doesn't want to hear it no matter how sincere i am. Thanks!
