I know S2’s innocence comments regarding OW sting. I totally get the feeling of wanting to hide out in a cave for a while.
You are the parent. You are Mom!
OW is like an aunt. And after a fun day of surf and sun and jet ski and excitement, it follows that son is going to say stuff like that. It’s ok. It’s really good actually. It’s much better than son coming back with horrible tales of mistreatment and lonely unhappy times.
Kids are allowed to have favourite aunts, uncles, friends, etc. - it doesn’t replace their Mom (or Dad).
S2’s feelings towards OW and his love for you, his Mom, are not mutually exclusive. You don’t need to compete or worry.
I grew up having favourite uncles and aunts; and I love them dearly. However, they are not my parents. Visiting with a favourite aunt is a fun time, no school work, no reminders to make your bed, and so on. It’s a bit of a fantasy life. Oh it’s real, but they aren’t raising me. And there is the big difference. Short term vs long term. Commitment.
You are his Mom. Son knows this. As he grows - He will show it. He will it for granted. He will ignore it. He will test it. He will cherish it. And many years from now, he will recognize just how deep your love is.
Enjoy the innocent expressions of son’s bubbly emotions. Young children are so unfettered and honest; speaking and living in the present moment. Enjoy it while it lasts.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
