getting fed up

Ever since the weak before Christmas Wendy's oldest daughter and granddaughter have been in my house but 4 days .Her daighter wasnt there for her when her late partner/spouse pasted away because she only cares about herself she is selfish when Wendy and I started to have feeling for each other and I was coming over to visit then later to move over here she didnt want me to come she only wanted her mother to be here for her when she needed her which for the first  few years was maybe every 3 months or so .Now that Wendy is dying her daughter feels guilty and thinks she is the only one who can do anything for her mother she is a control freak who thinks she is everything .her daughter Wendy's granddaughter is almost 9 years old and has a dirty mouth which the daughter doesnt do anything about but if I saya bad word I get a ear full . this daughter comes running every time Wendy makes a noise even if we are in bed sleeping I cant get any space from this person whom I dont have any respect for or even care about . I will never forgive her for taking most of Wendy's remaining time for herself .Wendy's youngest daughter and husband have always been great to me and treat me like family ,the youngest daughter lives near us and always spent time with Wendy . The oldest lives 2 hours away her choice to live that far away herself and her husband worked down here they moved there to be on their own and away from everyone. The youngest kind of feels the same way she feels she has been pushed back .                                                          The oldest daughter keeps trying to find this like alternative medicine to save her mothers life the one doctor cost around 1000 dollars a visit Wendy went there 7 times and the turmours got bigger and kept spreading so Wendy stopped going after almost 9000 dollars oh I think its a good idea to not give up but not once so far has the daughter offered to pay for the treatments we are trying to pay all the bills plus these treatments is getting costy the youngest daughter has lent us the money but we will pay them back .                                                                                                                                                                                                    I am doing my best not to go nuts and start telling the oldest daughter off and telling her to get out only because Wendy will always take her daughters side and I will make life worse in my house so I have to take what little time I can steal from her .When Wendy is gone I will never talk to the bit ch ever again
