I'm going to ask my husband to cut a trip to say goodbye to his aunt short so he can make Mother's Day
Why do you need to cut his trip short so that he can go home for Mother's Day?
I want to give my mother a special gift, we always do this on Mother's Day.
Maybe you should respect your husband this time to spend more time with his aunt as he may need more time to do so and just try to celebrate mother's day with you and your mom instead, just this time. It doesn't seem right that he should have to dismiss his family for your desires.
I'm frustrated it's Mother's Day and my husband hasn't showed up yet.
Well, he is on a trip and you should be more understanding about that, as he should also be understanding whenever you will be unavailable for an event. I hope you resolve this with him and just try to be more patient and kind towards one another so that you don't have unnecessary conflict with your husband.
