A girl posted asking for help, saying that her boyfriend goes to pay respects to his ex-girlfriend every year, and she doesn’t know what to do.

The situation is this. She said:
Every year around Qingming Festival, and also after Chinese New Year!
He drives more than 200 kilometers,
to pay respects to his ex-girlfriend who has already passed away!
Not only that, he also often visits his ex-girlfriend’s parents
to help them with some day-to-day trivial matters, resolve some troubles and problems.
The girl feels like
maybe her boyfriend can’t let go?
But he hasn’t done anything that betrays her.
Still, every time she thinks about these things,
she feels really uncomfortable and uneasy inside,
and she doesn’t know
what she should say—
whether she should understand him
or whether she should still feel bothered?
This is a real incident!
If it were you, would you be able to accept your partner doing this?
