My dm has been in a relationship with a man for over 10 years, he's from overseas and has spent majority if their relationship going to and fro. Dm said earlier in the year she wanted to go back with him and spend a few months there. I also have 2 dsis (17&19) who live at home so they would be home alone and left in charge.
The mortgage is paid on the house and dm has savings for dsis to pay for other bills (food, gas, lekkie).
I told her I didn't agree because it was a long period of time and it would ultimately be left to me to be on hand if there are any probs etc. I live about 15 miles away with DS and Dp.
She booked her tickets anyway for 2.5 months and we reluctantly we waved her off.
After about 2 months she announced she was extending her ticket and staying for another 4 months, missing an important family event too. Dsis and I were not happy and told her so, but dm talked about never having a holiday since she has has kids and how much she needed the break, continued to book her ticket.
Dsis (19) goes off to university in shortly (when dm was due back) so I stressed how import it was for her to come home so dsis (17) isn't home alone. Dm has ignored this and has now announced she is extended her ticket a further 3 months.
I am absolutely livid and think she's being so selfish. She's basically having an extremely long holiday and leaving the house and dsis to be sorted by me.
I can't even speak to her at the moment. AIBU to be so mad at her or do I just shut up and agree she 'really needs a holiday'?
