Rose and Mickey have an interesting relationship that causes quite a bit of stress for the both of them. Both have deep affection for one another but they are each searching for something more. They are tied to each other by their circumstances and past, but sometimes they realize that they are becoming very different people.
Rose wants adventure, excitement, and spontaneity. She wants to wake up each day and have a new experience every day. She is a wandering soul that will never be satisfied with a quiet life of the same thing day to day. If there is danger, she will be there in a heartbeat.
Mickey wants safety, comfort, and stability. He would love to repeat the same routine for the rest of his life and never think twice about it. Mickey needs to feel protected by having the security of a significant other to empathize with his life struggles. When Rose leaves him to go on adventures with the Doctor, Mickey feels abandoned and hopeless. After some time of being gone, Rose returns to find that Mickey has started seeing someone else. This is a turning point in their relationship because they both grasp that if things are not going to change, the two will be at the end of their relationship. They both have to decide which life they want to live and what they are willing to sacrifice. Rose decides to bring Mickey along on her adventures, which isn’t sacrificing much, but Mickey goes a ways out of his comfort zone again for Rose to help the Doctor, Rose, and Jack defeat the Slitheen. This shows Rose how much Mickey cares for her, but in the end it may not be enough to hold them together.
In my opinion, this is how a lot of relationships end. In life, we only look at our side of things, but someone else could be going through so much more than what shows on the outside. It is important to keep an open mind. The moment we are not willing to compromise on issues in the relationship is the moment the battle is already lost. One person can only do so much to keep the two together, and sometimes we have to look at how it is affecting us personally. Mickey will always come running to Rose because he is so in love with her, he would do anything for her. I feel like this relationship is doing more harm than good for him, and he will be a happier person if he just lets Rose go. The hardest part is realizing that sometimes we are not the best thing for the one’s we love.
