your husband should ALWAYS come first before your kids, your parents, friends, work, etc. He is second ONLY to God. Your kids will grow up and leave you for their wife/husband, and you'll fall behind them...your spouse is with you "till death do us part".
Although, let's get real, some nights it's like having to share a bed with that co-worker who's on your last nerve... But then there are the nights where it's like having a hot one night stand... Only you're perfectly okay with him hearing you fart after. ;) Yeah, I pretty much love being married to my best friend. <3
