Should I not have sent this?

I'm a nanny and just got told about my schedule. I have two families so I can still pay bills. But I sent this to my boyfriend of one year because we are living together. I heard that money is the number one problem in couples. Should I not have sent this??

"Hey, so I just found out a few things about my schedule. February 27th - March 13th : Grandparents come to watch kids. Only needed a few days.

March 18th - April 1st : In Florida. Not needed all days.

So I'll have to slightly budget which means no eating out during the times I'm not working as much. I'll likely find something short term since there's so much notice for March but I'm just letting you know."
