Hellow, I am 23 yrs old ( female)am kind of a loner sometimes, I kindda enjoy being alone, walk ar sit alone, I like to have my moments away from ppl, I have a freind, we got too close i feel, she calls me every day, I feel that she is suffocating me, she did nothing really, she calls me everyday, i can switch off my phone, i tried it once, she called me the other day and she was like: are you mad at me..etc. U know I understand her, but i dunno i don't like it when ppl get too close to me, like i said i feel they take all the air. she likes to complain and hear me complain, when i say nothing, she thinks am mad at her..I am sure u met ppl like me and her..?
Try to say something like this:
"I appreciate you a lot. Due to my personality I need more space in our relation. I want to call every second time and you to call every second time. I hope that is OK with you. I like your friendship very much."
