don't know about specific wazifa , generally make dua to Allah to bless your marriage.
If your wife left home 3 times already , it's time to give a serious thought about the married life . If u can't afford to live separately with your wife , explain it to her clearly . IF she wants to continue her married life , she must adjust with the joint family. If she does not want to consider it , then tell her to take the decision if she wants divorce .
As u 2 have a kid , give your best to keep the marriage . But if u 2 can't live peacefullly , offer Isthekhara salat to decide if it's better to end such unhappy life.
May Allah grants what is best for u .
