Would you be concerned about this?

My boyfriend of 16 months has not been on good terms with his nanny lately. That's why I was surprised when this morning, he texted her at 8AM this morning with 'Merry Christmas Emily 🎄❤🎅. Thanks for all you have done this year.

She replied with 'Merry Christmas xx'

Can't help but dislike the fact he put a heart on it and texted her early. Like she was on his mind and yet he says he does not like her 😕

Am I being unreasonable? I read it as he got up to go to the bathroom
