How to keep my husband whom i'm divorcing away?

i've recently told my husband that i'm filling a divorce.He changed and have been doing things out of his routine and habits. I know its human and desperate for him.A divorce will make him lose all.Custody of our daughter,our house and the need to bear maintainance to us both.But it is too late.I don't love that man anymore neither do i respect him.Things he does nowadays only bring annoyance and disturbance.Puts everybody at home,that include my mother..to uncomfortable moments. How do i stop him and make him understand to all this? This is my most difficult decision made and despite all,i wish he could be strong and understand why all this is happening.
