You NEED to show your Husband this and all the responses you get back.
I say... NO way.
45 minutes one-way... plus traffic... and then to go back home... is one and a half hours... just being on the road driving. And actually it will probably be more like 2+ hours... just to be her Taxi. And what about how will she go home????
PLUS with a 3 year old.
PLUS your Husband did not even have the decency to ask you, first.
No way.
I at one time, was taking my Hubby to work. He usually car-pools with my Mom. My Mom lives with us, they both work in the same area. So it is common sense, they do this. Car-pool. Which your MIL can do TOO.
Anyway, so when I was taking my Hubby to work.... it took 1+ hours, round-trip. That is how long it took.... in traffic, driving or idling... or just stuck in traffic. My son, who is 4.... HATED being in the car, that long. He HATED it and would tell my Husband "Daddy! I HATE being in the car... its too long... why can't Grandma drive you...." and it was a super unpleasant car ride with a 4 year old constantly complaining about the car ride.
Another thing is... we wasted over 2 hours, in the mornings, every weekday morning... just driving him to work and coming back home. Because, BEFORE we even drove him to work, I had to take my daughter to school, first. So that added even more time being just in the car, driving or stuck in traffic.
All of this, took a TON of gas... and wear and tear on our car. And, by the time we took my Husband to work... my son would be all so irked... and then on the way home, just too darn irked and tired from sitting in the car for that long... that I couldn't even run errands with him on the way home... without him totally having a melt-down. His 'patience' had been reached... at his limit.... just having to be in the car for over 1 hour.
AND... because of my having to take my Hubby to work... I then had to rearrange ALL of my morning appointments and my children's appointments. Too. NOT fair.
Anyway, it was really... an unpleasant ride for me.... too. And my son. And my daughter who then had to wake up earlier and go to school earlier... than usual... so that we could take my Hubby to work.
I took him to work... because, he simply had a childish whim that he didn't want to ride with my Mom... because she put the radio on too loud!
Anyway... I say, no way.
Tell Hubby.
Tell your MIL.
And make sure... they do NOT make you the fall-guy or the scape goat.
Even if MIL did pay for gas.... (which she should), that to me, is still an outrageous expectation... that you are being expected to do.
Your everyday schedule/appointments/errands for yourself or your Son... will have to be also rescheduled around being MIL's "taxi driver".... because it will take up so much time. And to me... that is really.... not fair.
Just because you are the Daughter-in-law... it does not mean you have to do that.
Just because you are the daughter-in-law... it does not mean that you have to say "how high" when they ask you to jump.
NOR should this be for forever... or whenever they say you have to do something. YOUR Husband.... should be more responsible... for HIS Mom... and helping her... himself.
I say... tell your HUSBAND to drive his own MOTHER... to work.
Period.
That is not your "job." It is his.
That is HIS RESPONSIBILITY.
Period.
It should have at least.. been discussed, with you, FIRST.
all the best,
Susan
