If you wish the marriage to sustain then file a case for restitution of conjugal rights and wait whether she joins you. If you have decided to divorce her then go for Mutual Consent Divorce, as your wife is also agreeable for MCD and before that you make your stand very clear to her that you will be the custodian of your daughter after divorce. Whether you want to pay her maintenance/compensation etc is left to your decision. Your wife can not claim share in your mother's house after divorce.
