Is my husband taking advantage of my kindness? Read description below

A friend of mine told me that she believes my husband takes advantage of me. I don’t think my friend meant any harm, but now I’m second guessing my relationship. My husband and I have been married for 8 years. We have 4 kids, ages 7, 5, 2 and 6 months. I’m a stay-at-home mom, while my husband works a physically demanding job 45 hours a week to support our family. Because my husband works such long hours, I like to go above and beyond for him at home. Some nights I’ll run him an epsom salt bath when he gets home. I also rub his feet and give him fully body “happy” massages multiple times a week. Those are just a few examples of the little things I do to go above and beyond for my husband. My friend doesn’t know the intimate details of my marriage, but she knows I like to bring his plate to the table, sometimes run his bath water and massage his feet. To make a long story short, my friends asked if I enjoyed being my husbands maid??? She also told me that she hates watching my husband take advantage of me. She told me that there’s no reason for me to run a capable grown man a bath. Apparently she thinks my husband only married me because he knew I would be his in home maid. I genuinely enjoy doing things to make my husband happy. He works long hours and still helps out with the kids when he gets home. I do handle most of the housework, but he always washes the dinner dishes for me. My husband also doesn’t ask me go the extra mile, I do it because I want to. I feel happy with my relationship, but now she’s got me second guess my actions. My friend is also a stay at home mom,but she thinks I’m being to subservient.
