When you were on your previous relationship, there are certain decisions that you cannot just decide alone. You should always ask your partner about that. So now that you are alone, you should learn how to decide on your own. In my experience, I really wanted to have a tattoo. But since before I'am not allowed to because I have to asked permission with my ex, so after our break up, I went to a tattoo shop and ta-da, I experience the pain of having a tattoo, yet it fades away after a while. Just like the hurt I felt, when my ex left me.
