She's right, we are, because our values are completely different. But when I'm with her I don't question certain remarks that she makes, partly because they sometimes leave me completely speechless and partly because I don't want to be hurtful. And she doesn't really listen to me, just sort of assumes that our ideas must be similar. So I don't think she realises the reasons for the changes in our friendship.
We both have young children, my DD is 17mths and hers is 14mths, but this has made our lives more different rather than more similar. Also I'm pregnant and she moved further away a while ago, so we see each other less often than before. I wasn't really bothered about seeing her less but she's recently brought it up - not the seeing me less, because that's about practical things, but the feeling that we're becoming more distant. So, do I keep my mouth shut, try to make a bit more effort, but accept the continued drift; or do I tell her and risk a big falling out? I'm feeling guilty about it because since she brought it up I've realised that she needs my friendship more than I need hers - I know how callous that sounds, but I'm sure it's true.
