1. He dumped his girlfriend.

2. He broke up with his girfriend.
3. He __________ his girlfriend.
----------------------
Is #1 the same as #2? What other expressions can we use which have the same meaning?

1 and 2 infer she was garbage and he got rid of her, in my opinion. The first sentence is trash talk. "Broke up" is understand a relationship was "broken" and couldn't be fixed, like a glass dish.

Other words: "ended the relationship with his"
"separated"
