We've all heard that love is patient and love is kind, for these are some of the greatest words in the Bible. How many of us remember "Be Kind, Rewind"? Yes, If you are old enough to remember VCR tapes from the library you might have seen that prominent red on white sticker that reminds us all to think of the other person before filing away that video without rewinding it back- the way you found it.
Marriage for women (and probably men) is like a video tape. We as women have memories that play back at the best and worst times and we play them over and over again, whether it's when we are stewing about that awful thing our husband said or whether it is to replay in our minds the "happy days" that we think are long gone. After 8 years of marriage happy days don't have to be archaic. You just have to remember that marriage is about growing with your spouse, not leaching happiness out of your spouse.
You say you don't find your husband attractive. Obviously you are talking about physical attraction, because in the same paragraph you said he was a great dad and that he really loves you. Has that stopped counting for something? When you first met your husband were you looking for that sublimely handsome and sexy guy to marry who could be the worst jerk in the world, or were you looking for a man that you saw as good/great father material who would love you even though you fight with him? It's all about priorities, isn't it? You obviously liked him at least a little if you have kids, right? You weren't afraid to have kids with him because, at the time, you valued his character and manliness and probably love and leadership in your home.
When did YOUR priorities change? Do you WANT to be the good/great wife and mother in your home, or do you want to be that woman that is so focused on artifice and externals that you ruin your own testimony before your kids and your church. Is indulging in the fantasy of other men's externals worth the angry and selfish persona that your discontentment has created?
If you WANT to love your husband again, why don't you sit down and take a few steps in an effort to change yourself? Sit down and watch the movie called "Fireproof" together. It's interesting. Then look into a study called "What Did You Expect" by Paul Tripp. After that, why not just take regular time together to figure out what you both want- not to see how screwed up things are, but to remember why it was you two made it 8 years with kids. You chose to marry the man... now chose to be a godly wife to him.
