A person's spouse always has to be the most important person in their life. They should come in "second place" right under loving the Lord first. God is devoted to making strong marriages and He's the one that will keep the two of you together with great love and affection. He has a way of increasing the right kind of love in a person and will alter quality time to fit a couple's need. Centering your lives around God and his word gives you miracle power in this busy world for extra time together and for each family member. Be sure to include God in prayer at meals, travel, daily activities etc. God and his word is the miracle bond that keeps families together under every circumstance. He has a great investment in your family and wants to bless you.
If it seem like he's giving more attention to the children than to you, examine your feelings. Why am I not happy about how my spouse treats our children? Maybe he's young at heart and just likes to play. Are you participating in his relationship with the children or are you sitting on the sidelines feeling jealous?
Are you interesting enough that he wants to spend time with you or do you nag? If you're asking him to do something every time he's with you, he won't want to be with you. Make a Honey-Do List and hang it on the refrigerator and never nag again. Help get jobs started if he isn't a self starter. Doing half a job with love is better than doing a whole job by yourself. Ask God to help you with resolving the problem. It could be a simple adjustment like planning activities for the whole family or learning to participate in something they like to do, even though it doesn't interest you.
