You may have seen my threads recently.
Basically in a nut shell she has a very ill partner who is going into a home, she can't pay her rent without his carers allowance and will have to move into a housing association property, she is slaging off FIL (her ex h) and talking about things that happenned 30 years ago asif it happenned last week, she told lots of hurtful lies about dh and I to his bro and his wife and could have caused a huge rift, she is slagging off dh and his bro to her friends, last week she faked being attacked by her neigbour to gain our sympathy, she is drinking lots every day and smoking like a chimney.
She has not seen my ds in over 8 weeks (she lives 5 mins away) but last night called to say she will pop round next week asif nothing has happenned.
Dh and i need to talk to her, I am very angry at her, but feel she has underlying issues (poss Bipolar?)
Any advice on how to tackle this?
