Friends checking out?

Is anyone having an issue with friends just checking out on you now that you are pregnant? I have this one in particular that was ALLLL about my husband and I getting pregnant said she would be there and involved....then once it happened she fell off the face of the earth. She forgot my drs appointment that she swore she HAD to be apart of and that she would just cry when she saw the baby on the sonogram.

She is now spending time with new people and tagging them as her BFF and I kind of just don’t get it?

Has this happened to anyone else??
