Was speaking to a new Mum today about her letting some friendships end, as particular friends were not adapting well to the changes in her life resulting from having a baby.
I lost two friendships.
One was a life-long friendship I'd had since infant school. She always thought her life was better than mine and got used to perceiving me as being 'beneath' her with regards to accomplishments in life. As my life started improving in her eyes - I got married, bought a house and had a baby, she got quite jealous and started a range of spiteful behaviours. The spiteful comments she made when she visited me with my newborn were the final straw.
A second friendship ended because she did not understand that I could not make last minute arrangements to go out, or that I may have to cancel last minute due to the baby. She got quite arsey with me on a few occasions about it. It was a side of her I'd never seen, and it was not nice.
I think that when big changes happen in life, like having a baby, it really shows who your real, true friends are. Obviously, I maintained some friendships - with people who tried to understand that things would be slightly different now. I still feel sad about the friendships that didn't make it though (all the good times and fun we had). Even though I know deep down that they probably weren't true friends.
