i have a friend who i have been friends with for over year and has been a tower of strength to me over my recent health issues (i had a mmc at beginning of dec) and she has been amazing, she has issues in her life too that i feel i have helped her progress and move on, so i think we are good friends when in need are there for each other. we are both married, i have no kids. she has 3. but recently i feel she is distancing herself from me. i appreciate we have different commitments as she has a family that will always come first and i dont so things are more easier for me to be more free spirited. i sense when she talks to me she is now snapping at me and im bothering her and she just replies when she can be bothered. she always says she is busy. yet but as soon as she says that i get notifucations for game requests on fb. she is quick to pull me up on things i do wrong and that is something i need her to do otherwise i will never learn to correct things i do wrong if i dont know ive done something. yesterday she told me my messages to her are becoming unpleasant and i wasnt aware they were. i apologised - i told her that sometimes her messages come across as rude and she got all defensive. she got me the most lovely christmas present and the thought and love that came with it made me cry!!! i feel were pushing each other away and i need to know how to stop because i know i need her to be around in my life. but i struggle with friendships and maintaining them.....
what can i do to keep her friendship?
