So...
At first u have to show her all ur feelings, just to make sure dat u didn't leave her in the past for nothing, n also try to compensate her with all of wht u can do n yeah maybe she is angry with her sister in law because of jealous so, don't ever put her in compare between the both
Love n care sometimes depends on feelings rather than deeds
So, for the second time in gonna advise u to take care of her by showing ur feeling, ur love to her
