Welcome to the forums!
The decision of getting a same species companion or not would mainly depend on 2 factors. The daily time you are able to spend with your budgie and your budgie's very own personality.
By paying close attention to Felipé's behaviour you will be able to have a better idea on how to proceed.
Since you are better acquainted with your budgie's ways, you are in the best position to reach a conclusion when it comes to Felipé's overall happiness.
If he is generally playful and energetic, sings exuberantly and bobs his head up and down, then he is happy with the way things are.
Depending on personality and if they are more on the shy side, some males can in fact be more quiet when compared to others. And usually these shy budgies thrive and are most happy when they have the comfort and support of a same species companion.
If you notice signs of depression in Felipé, he can in fact benefit from having a friend. The fact that he has ignored his previous mate doesn't mean he will do the same to another potential mate, if he was bonded to the mirror that would partly explain his behaviour. Mirror toys can be quite troublesome especially for single budgies.
If you do decide to get Felipé a new friend, it doesn't necessarily have to be a female. Male budgies can be the best of friends.
When bringing a new pet bird home, it's also best to quarantine the newcomer in a different cage and room away from your current budgie. This is done as preventative measure to avoid any possible illness from being spread to your Felipé.
Good luck with your decision!
