I would say that without a doubt some portion of my niece's problems were his fault.

But the subject line "manfriend issues" seems to be comparing me to him and "implying" that I was the one creating problems.

I don't appreciate that.

I was the source of respite, fam.

Also, I knew very little of how my brother interacted with his SO compared to his relationship with his daughter.

What exactly do you know of my nieces problems, by the way?

Not much? Then kindly leave me alone.
