Am i whipped by my wife?

I am twenty one and have a twenty year old wife and two young children under two years old, Things are great between us and i love her to death but lately i feel like i have given up trying to win arguments or get my way, I tried fighting it and all that would happen is we would ***** at each other for about a half hour and than i would end up doing things her way anyways so i say f*** it, I will skip the middle step of fighting and do what she says, once i started doing that she has taken advantage of it and walks all over me. she knows i wont bother to fight her anymore so now i feel like a pushover and a slave, she just enjoys telling me what to do and watching me do it, even if its something she could do easier. for example she will be standing right next to the tv but she will tell me "come turn it on than i say" your closer, cant you get it ?" than she will say" yeah... but i told you too" than smile this sexy evil way that just makes me melt like butter. she does this with alot of stuff, i think she knows i also fear divorce and child support and uses that to indirectly control me, I feel like a pansy but shes happy and I am happy i just wanna know if its excessive
