I will try to keep things quite generic.
I have been best friends with this person for a number of years. Our children went to the same school, so that is how we met.
My friend is very dramatic about everything and likes to embellish stories to make them sound worse than they are because they like the attention.
There has been several instances over the years where I have been told certain things, only to later find out that they are completely not true. When approached and asked about lies, they have always been brushed off.
Over the years I have known them, I have watched relationships with men fail, friends disown them and their family stop speaking to her. I am literally her only friend now.
Lies include:
Telling me they has Cervical Cancer after a screening - she had some unusual cells that were treated. (I've also had this done, and its nothing "major").
Cancer of the lungs... and the most recent one - cancer of the kidneys (small cysts found in both cases)
Lying about the father of their children
Lies about why partners have ended their relationship with them.
Lies about their health in general, making it out to be worse than it actually is, therefore always calling the ES and going to the Emergency Room, their insurance bills (OOP are in arrears).
Their children are effected by their behaviour, (they don't go to school properly and have a chaotic home life) and they don't really have anyone to protect them apart from me.
Anyway, they spent a significant period of time in hospital recently- the doctors couldn't work out what was wrong (there was nothing major, she just kept saying something was wrong), so they released them home and they have been fine! They told me that their youngest's (1.5 year) father was being really nasty via text message and threatening to have the child permanently to provide stability. So when I saw him, I asked him about it. He said nothing, but handed me his phone and let me look through the text messages - he has been nothing but supportive and they were the one being nasty to him, calling him names and making threats to stop visitation!
Anyway - I'm getting to the point that I am really fed up with all the drama, with all the lies and with all the manipulation. I am not a mean person, but I find myself raging to my wife about their lies and questioning everything. I really want to end this (toxic?) relationship, but I really don't know how to. The kids are important to me, and I don't want them left without any protection from their drama and lies.
What should I do?
