Should I question this more or am I overthinking things?

My husband works away (M43) comes home every 2 weeks for a couple of days.
We have been married under 15 years and have young children. I (F 45) stay at home and look after them/do the parenting things and look after the house.
He has come home and started to do the weight loss injections as he’s obese and has not been able to shift the weight on his own and said to me very randomly ‘ I was worried that working away I would come home and not find you attractive anymore, but even looking as you do now, hair up messy, no bra, hot and sweaty from the heat, I do’ and walked away.

Initially I didn’t think anything of it, but now it’s bugging me!

Yes I’ve put on about an extra 10 kilos in 15 years from birthing 4 children, I don’t go to the gym I don’t have time, I can barely keep up with what I need to do in the house and with the kids to even get time to bathe before midnight and never get time to myself.

I just feel a certain way about this and I don’t know why, or even how to phrase a question to bring this up with him.

Do I need to? Am I starting to over react in wanting to ask him wtf makes him so special to say that to me?

For information I’m 5 years into perimenopause, on HRT and one of my children is complex autistic so I run on fumes 100% of the time and my mood can be frayed by exhaustion.
