I’m sure some of their behavior is annoying. But you’ve got to do some soul-searching to determine why it feels so personal to you.

Occasional, fleeting envy or resentment at someone’s oversized Easy Street mansion is always normal, as anyone who’s ever logged into Facebook knows. But dwelling on it can make your own negative feelings worse and often indicates stress or insecurity about your own life. If they’re good people overall and still well-matched to you as friends (a big “if”), you’d be wise to examine your own feelings and see if something deeper has been getting your goat lately.
There’s no doubt that this is an excruciating situation to be in, but I think you realize that staying with him solely because of his dad’s diagnosis won’t do anyone any favors.

When the initial shock wanes, you can initiate discussions about your feelings. (This also buys you time to make sure that breaking up is what you really want.)

But if he’s willing to be one of the few cases where “Let’s remain friends” actually carries some truth, you can continue to be a support for him and his family though you’re no longer his girlfriend.
