| My husband is an engineer. Since we met, he has always been the rock in my life .I knew he had his feet 1 planted on the ground, and it seemed that no matter what else went 2 , he would be the constant one. Three years of romance and two years of marriage later, I began to feel 3 of him because he never brought me flowers, he never 4 me, and nothing had changed in our marriage. After 5 , I finally told him I wanted to be 6 . He just sat there, speechless and didn't even know 7 to say to make me stay. Finally, he spoke, "What can I do to change your 8 ?" "I'll stay if you have a good answer 9 this question," I replied coldly. "If I asked for a 10 growing on a cliff, and getting it for me 11 certain death, would you still do so?" His face grew troubled. "Can I give you the answer tomorrow morning?" With that, my heart 12 . He couldn't even give me an answer 13 away. The next morning, I found he was 14 .

Every time you leave the house, you forget your keys. I need my legs to run 18 and open the door for you.... that's why I cannot pick the flower for you..." With tears 19 from my eyes, I opened the door. And there he was, with an extremely worried look on his face, waving the packet he had in his hand in front of me. Just because someone doesn't love you 20 you want him to, it doesn't mean that he doesn't love you heart and soul. | |||
