United you will stand and divided you will fall. :(
That's a tricky question, He does have an obligation as a husband to fullfill his part in your marriage. Have you tried talking to him. If that is not working , than I think that he is not fullfilling his part of the marriage vow's. If he is doing things that are leaving you and your children in jeaopardy, then maybe it's time you took a break if you can provide for you and your kids without him. Im not saying divorce him , or start a new relationship, but if you were hired for a job , and didn't perform your duties, how long do you think it would be before you got fired? He may need some time to evaluate your relationship and his obligations. You to......
Yes. You made a commitment. Now it's up to you to learn how to communicate effectively and help the man become a better person. You'll both be much happier. You were brought together for a reason, now put a little work into it and stick it out. Everything will work out fine.
It's up to you doll but if you have children with him and he's letting them down then maybe not.
Maybe leaving him could actually be good for him as a person. You really should look after yourself, you only have one life.
What leads you to believe that the responsibility for taking care of the family falls only on the man? Maybe, if he felt you were willing to share the load, he would be more motivated to do his share.
He is your husband, you are bound to him as long as he shall live and you are the one that agreed to that. You pray for him, and you be a good example to him and you submit to him and you read the Bible.
