I have two very nice friends - A & B - whom I see every 6 weeks or so.
I am currently a SAHM and have a DH with a good job ( this is relevant. Not a humblebrag) but we are by no means multi-millionaires.
Friend A is going back to university to retrain. Obviously, this is going to be very expensive - particularly as she has Dc who will need full-time childcare.
The last three times that we have been out, Friend B (who is incredibly generous but probably had the least disposable income out of all of us) has said - in front of friend A - that friend B and I will pay the bill as friend A is going back to study and it will be very expensive etc. Obviously, I've said this is fine. Friend A (who can be a bit tight) as thanked us both very nicely and accepted with alacrity
As I've said, DH and I are certainly not multi-millionaires so how do I handke this going forward? We are going out next week and, actually, I don't want to split the bill again and pay for friend A. I completely understand that it is very expensive to go back to re-train and that she and her DH dont have huge amounts of disposable income. But I kind of think that's something for them to deal with.
Am I being very mean? How can I say "no" without looking terribly rude? I know I can obviously just say "no" when the bill comes but I would like to try and resolve this gracefully and without causing offence or looking like a tight arse
