I had a similar incident with a family member of mine.. long story, short, i got pregnant when i was still in high school and she had jst had her second miscarriage, when I found out i was pregnant, she got pretty upset and bothered that a high schooler could get pregnant so young n she was having so much trouble..it took her a couple months to accept it but my husband and i invited her to a couple ultrasounds n constantly kept her updated and the more we made her a part of the pregnancy the closer we got... and she is now my daughters godmother and loves her tremendously...
She will come around. she is just going thru a rough time and there is nothing that you or anyone can do about it... So sorry to hear that though that she had to go thru that.
