Never marry a man that you cant respect and that cant or wont take the role as head of the household. My husband when we got married said he was a christian and went to church so I thought that was all that was needed. Now I know better and will teach my kids to make sure their soon to be spouses have a PERSONAL relationship with Christ. I wasn't much better than my husband at that point in my life but please make sure and see the evedance not just take his word for it. Does he spend time in the word? Do he seek Gods guidance about everything? What kind of father do you want for your kids? Dont think you can change him, only God can if he lets Him. If you want to stay with him and pray he changes thats fine, just dont marry him until you do. Christians need to start taking the til death part more seriously and letting God have a hand in picking our perfect mates, not just lust, lonliness, or satan. I dont mean to be harsh with you, more harsh at myself. Just really dont want people to make the mistakes I did.
God Bless and Ill be praying for you.
