I have been friends with someone almost ten years. A couple of years into the friendship they told me they had become pregnant aged 12 and the baby was stillborn. She went into a great deal of detail about the whole thing. While I completely sympathised and cried along with her I wished she had told me another time as I was days away from giving birth myself. I felt awful for her dealing with that, especially at such a young age.
Since then we have had an on off friendship, she can blow hot and cold, make rude remarks, be very judgemental... If i am honest I think I would have ended the friendship long ago but I make allowances for how messed up she must be after what happened to her, and she often excuses her own behaviour as she suffers depression and mood swings as a result of the stillbirth.
The other day I was out for lunch and ran into her mother, who my friend does not see often now as they fell out. We don't really know each other, except to say hello in passing, but had a coffee after my friends had left. She started complaining about her daughter and how she makes bad decisions etc, and I mentioned how what happened as a child must effect her every day. The mother was gobsmacked, said it never happened and that it was a complete lie. She told me her daughter is a compulsive liar. This was verified by her friend who lived next door to them when my friend was a child, who would have surely noticed a pregnant 12 year old and known of what happened. I feel certain from their reactions, and from my friends past of lying and doing things for attention that my friend lied.
Part of me feels my friend must be mentally ill, and I should try and help. But mostly I just feel sick to my stomach that she could lie like this, distress a heavily pregnant friend with this lie, excuse every bad behaviour.... I just want to cut her out my life, even though I know she has no other friends.
Should I be more understanding of her apparent mental illness? Aibu to feel completely disgusted and manipulated. I just don't want to speak to her again, not even to tell her I know the truth. She has told others this lie too.
