To me commitment in a relationship is the wanting to be there through the ups and downs. It's facing the hard parts of life, love, and relationships, and not picking and choosing which parts you want to experience with a person. To me its not just taking the easy way, but facing the things we struggle with and not being afraid to face it and share them with our partner(s) and letting them do the same. Its being there to enjoy the good times, while being a source of comfort and support through the difficult. To me its saying I trust you and I'm willing to let you into my life to know me as I am inside and out. It's wanting to grow as a person so you can become a better you.
I know that my idea of commitment may seem kind of simplistic, but to me being commited is simple. you either are or you arent.
