Yes of course! It’s an important life lesson that even if you feel like
tit, you don’t bring other people down! ‘Treat people how you would like to be treated’! I know they’re only children so don’t always understand the power of words but I was bullied at school and never got over some of the cruel things said to me, so I sympathise
I don’t have kids but my partner works away every week which I know isnt quite the same as your situation at we see eachother at weekends, although at the moment he’s away for a three week stretch, so I understand how lonely you must feel

It’s taken 2 years of living alone in his house and I’m still not totally used to it!
