I have 3 dsd. The 2 eldest are 19 and 17. MY DS is aged 17 and learning to drive.
DSD1 and 2 have passed their driving test. DSD1 lives with Mum more than DSD2 and told us that Mum was paying for half her driving lessons. DP doesn't believe this but paid half anyway, suspecting that DSD1 was paying for the other half herself and was protecting Mum. It took her 18 months and 6 tests to pass. DSD2 took 4 months and passed first time. She did it the way DP asked and DSD1 didn't. DP paid for all DSD2 lessons as Mum refused to pay anything for her.
We bought DSD1 a car, insured and taxed it for a year. DSD1 is in full time work and we don't ask her to contribute to our home. DP regularly takes her out for meals on her own and has organised and paid for several repairs on her car.
DP has up to this point refused to provide DSD2 with a car. He wants her to be on my insurance and I have done this but feel very uncomfortable with it as I have now lost the use of my car a lot of the time. There are legal issues that he wants me to swerve. Basically I am the main driver but he wants her to have unlimited use of my car. This makes the insurance invalid but he is pushing me to "stop being so correct and everyone does it". I have explained that DSD2 would lose her driving licence if caught being the main driver when it is claimed that I am.
Because DSD2 is planning on going to uni, he knows that she won't be able to afford to run her own car, so feels that he would have to run it for her for many years. He feels this is unfair on DSD1. He has told me that if we get DSD and my DS a car to share, that he has to give DSD1 a lump sum of money each year to "make up for it" and to keep it fair. I have told him that he is comparing apples to bananas and as DSD1 has made the choice not to go to uni and work full time, then she is capable of running a car herself and he doesn't have to give her hundreds/thousands of pounds (which we don't have!) to make up for it.
I feel that I have to be the bad guy and tell DSD2 she still has to walk or get public transport, which is a bit unfair when DSD1 has a car she can use as she wishes.
I am feeling emotionally blackmailed. If we get DSD2/DS a car between them, then he will spend money we don't have "buying" DSD1 to stop her feeling jealous.
What is fair here?
