Key ingredient to every spell is the will and the intend .It is desire ,passion and the drive to stand for yourself and manifest (point out across ) your own opinion and ideas .
However if you can not stand for yourself even with words and actions how you will stand with other not so conventional method ?
The power comes within not from outside .Outside circumstances only push us to limit and either crush us or either make us strong .Which one of those two you choose to be crashed or to be strong ?Your magic is as much powerful as you are .
Go talk with your husband and mention to him how his parents are treating you .If he is true to you he will take your side and you together can have family meeting so everyone can speak for his feelings and how this situation reached such bad turn .
Hiding and crying hidden will not resolve nothing ,but only will poison you internally .
In case that they really do not care for your feelings and you have exhausted any other method i would call upon Justice and Angels for protection and to be guided away from this people .Also if your husband have no desire to stand for you i wonder if this relation is worth saving ?
I have found myself in similar situation lately and i sat him down and told him if he is not willing to accept me and treat me as equal with right of vote when it comes to our house and our life there is not point us being in relationship .If you do not stand for yourself first who will ?
You also may look for courage spells if you find it really hard to speak for yourself .
