Divorce Support Forums: Tryin to get divorced

I have grown out of love with my wife. We have been married for goin on 7 years. We have 2 children and have another on the way. None of the children have been planned. I love my girls very much and do not want to lose them. She does not have any intrest in keepin up a home. She does not help with house work and does not listen when i ask for help. I am workin two jobs and come home and work around the house till 9. I ask for help but she does not listen to my concersn we have these type of arguments every month to couple of months. She does not see this as a problem and is doin less and lessto help everytime I ask. I do care for her but I can not live like this. I need someone who wants to be wiht me and help me. We have grown apart in other ways also. Our sexual wants are diffrent. I want more and she does not have a urge or want. I want to get out of relationship, but do not know how to go about it. I kown there are goin to be hurt feelings and problems, but I do not want to hurt the kids or lose them. If any one has any suggestions as of a course of action I would gladly accept any help.
