Autism and relationship struggles

Hello! My name on here is going to be Shark. I’m new to this app and i’m looking for other autistic individuals to share experiences with and give support and advice on social things. I’ve been having a hard time balancing and processing my own needs and those of my friends and it’s starting to cause a rift in my friendships that i thought were solid. I have always had a more difficult time in groups but usually any time my friends want to hang out it is in groups so i will find one person to stick to since switching between conversations or paying attention to many people at once is difficult. They have recently started to complain about more to the point of sending me long rants complaining about it and i am not sure how to get my views across. It’s not a nice change and it seemed very sudden to me so I don’t know how to manage it. Does anyone have any similar situations or ideas on how to deal with it?
