@ceajallo,
She is 26 years old, an adult and able to make her own decision!
The father (you) brought her up and educated her - that's what all parents
are supposed to do, however, when they're adults they need to live their own
life and this includes choosing their husband or wife. Your job is done!
Be happy that your daughter has chosen a good man who also obeys by your
religious rules. Don't interfere with her happiness - it will haunt you otherwise!
