- stick to right to residence and co-extensive maintenance for children under DV Act.

- collect reasonable evidences of his extra marital affairs.
- Opt for marriage counselors few sittings to re-learn how to grow closeness with growing –up children and earn their respect towards their natural mother instead of they also alienating you listening to one side versions of natural father.
- Talk to other woman in his life especially her elders and cause upon her indirect social pressures so that she leaves your husband.
- right to residence is only granted under DVA ct and in such long marriages with extra marital angles that is the only way to subsist a live marriage for sake of growing-up children.
Etc. etc.
Limited way-in(s) you have if you don’t want divorce for the sake of children.
