Grammar fix
get together
to meet with someone socially
to meet friends, family, or other people for a social reason, often to spend time together or celebrate something.

Hear it in context
Notice where the phrase sounds natural.
We usually get together at my place on Fridays to watch movies.
I think it's important for families to get together regularly because it helps everyone stay connected.
Fix the pattern
One small grammar move makes it sound right.
Not: Let's get together with on Saturday.
Say: Let's get together on Saturday. / get together with the others.
'Get together' stands alone or takes 'with + people' — not a dangling 'with'.
Which sounds natural?
Tap the one a native speaker would say.
