There are two kinds of name you can have.

Your username is LoveAshley89 (and, for situations requiring a surname, "Resident.")  This is the name you created when you signed up, and you can't ever change it.

You can also create a Display Name, and you can change that as often as once per week.  You can set your Display Name by editing your Profile.

If you absolutely hate your username and you have not yet accumulated a lot of stuff, you can simply go through the signup process again and create another account with a different username.  You can then either delete your original LoveAshley89 account, or keep it as an "alt."  Many people have more than one account and use their alts for various purposes.
