“Looks like you'll have to fend for yourself for a few days.”
You've been asked to go on a business trip. You've just told your husband about it. He doesn't do much cooking or cleaning at home. You tease him by suggesting that it will be difficult for him when you're gone.
Looks like you'll have to fend for yourself for a few days.
This phrase can be used when you're guessing about how something is going to turn out when it's finished:
It looks like the Yankees are going to win this one.
However, it is also used in situations where something has already happened, and you have to tell the bad news to someone:
Sorry, it looks like we had to reject your loan application.
Saying "it looks like" something bad happened is softer-sounding than simply saying that it happened.
"Fending for yourself" mean surviving without outside help. For example, if a group of people gets lost in the wilderness, they will have to "fend for themselves".
It's common to say that someone has to "fend for themselves" when the main caregiver in a family (usually the mother or wife) is away from home for a few days.
