Is this in the sense of breaking up, or in the sense of leaving his company?
As an icelandic native i was sure this sentence translated to "She beats him"..... I was wrong
Someone can define for me the difference between ä and e? When I hear, they sound the same.
E is said with smiling/ leende lips, like E in yes. Ä is broader, with open mouth. Listen to Ett vägmärke vid vägen http://el.forvo.com/search/ett%20v%c3%a4gm%c3%a4rke%20vid%20v%c3%a4gen/
Swedish sheeps say "bää": Bä Bä Vita Lamm (med text) https://youtu.be/YY7PF41b9Aw
I guess your problem is short ä/e, as in "lämnar"? Unfortunately they are the same sound (except in some dialects).
