My partner is extremely lazy and is not as enthusiastic as I am about our business which we started an year back she hardly contributes anytime and effort in it. What to do I am really frustrated and when I talk to her about it she gets angry and fights and argues .
By partner do you mean that this person is also your significant other besides being your business partner?
No one 111 @jarul
So you should do what all adults do text her. Send a long ass text that she is forced to read without arguing or cutting you off
