If implementing both Observer and Observable interface to the same class is not good should I add separate classes to avoid that?

It sounds like you are implementing the Composite pattern. You have a Composite Observer that receives events and then emits them to its children. Combining the Observer and Composite patterns is perfectly acceptable.
