I have a friend who I see irregularly as we live far apart and have different life styles. She's generally been a good friend. Makes an effort to attend special occasions and is always warm whenever we meet. However, I know that she is struggling to conceive and is in her mid 40s (I'm nearly 10 years younger) and I have a 1 year old son. I've noticed that she's starting to not want to meet up with me recently. I'm always initiating. We don't meet up with my son but she'll always ask after him. I don't talk about him constantly either. Should I back off from our friendship and give her space? Or carry on initiating but accept that she might not be up to meeting?
