I am commenting because I have a similar-ish situation. One of my guy best friends for a long time has been very very affectionate and makes it clear that he really cares about me, which is sweet and I care about him, but it became a little bit overwhelming for me. I got married, and my husband was wondering about this guy, and the things he would say to me. He would always ask me to meet up for dinner, for lunch, for a night out. I much rather to meet a group of friends all at once, as I do like to spend time with my husband at The Weekend when I can. It’s not anything against my friend, it’s just I suppose there’s other things that have a higher priority, and I found him asking me every single week to meet up was getting tiresome. I have a full time job etc and loads of other responsibilities, I don’t have the time I used to 10 years ago. Ask yourself if maybe there was anything that you said that could have crossed a line for her. It’s lovely that she has a friend who cares so much, I would say maybe give her a bit of breathing space.
