Firstly, I'm very introvert and prefer to have a few close friends rather than a large group of casual friends. I'm also quite shy, and think i probably have some form of social anxiety, which means that i tend to cling on to the friends I do have rather than happily going out and making new friends.
I have one friend who i used to work with and thought that I was very close to, we spent quite a lot of time together socialising out of work and I provided a shoulder for her to cry on during a horrible break-up. But since the beginning of this year, i've felt her getting more and more distant. She started a new job and has developed a new group of friends, it always seems to be contacting her first, when we meet up we have a laugh but she often seems quite distracted, doesn't share personal stuff with me in the same way that she used to etc.
A few times recently, i've thought that i would just wait for her to get in touch with me and see what happened, but then after two or three weeks something will remind me of her and I'll send a message. I had lunch with this friend yesterday, and when i left instead of feeling happy that I'd seen her, I felt sad that our friendship had faded so much and still feel sad about it today. I feel I've got 2 choices: accept the friendship for what it is now, someone i meet up with for a casual chat and nothing more, or step away and wait to see how long it takes for her to contact me. Does anyone have any advice, suggestions, or just kind words to make me feel better about the situation?
