Close friends for around 8 years, she’s happily married with children, she’s late forties, ten years older than me. We used to discuss everything, were very open with each other and to my knowledge I’ve not known of any issues in her life (of course there may of been - I have been thinking about this) anyway I got pregnant around 3 years ago, unfortunately miscarried and still trying to get pregnant. Anyway as soon as she discovered I was pregnant she stopped inviting me over, out to places etc then all contact came to a complete halt. I carried on texting etc but got the message when she never replied. It’s been almost three years and we’ve gone from close friends to nothing. She does like a drink (I used to, but since we lost baby and have been actively trying I don’t anymore) but all of her close circle go out drinking weekly, and any events are always alcohol related. When I’ve thought about things afterwards pretty much everything we did together involved alcohol, we never went for walks or breakfast etc like I do with my other friends. I’m fully aware friendships fizzle out, so maybe that’s what happened rather than me thinking it was because I couldn’t join in anymore?
