What if ask friends to look after my pets and not my girlfriend?
That is curious. Do you not think your girlfriend can look after pets?
No, she is clueless with animals
It seems like this may be a good chance for her to learn don't you think? She needs to feel like you trust her in all aspects of life.
Yeah but I want to see if she can actually manage to look after the pets before I leave her alone with them.
You make a good point, but do understand that she will feel bad that you don't trust her. Maybe come up with an excuse of why you are leaving them with someone else.
