How do you respond when somebody you have never met in person and only exchanged a sentence or two with online suddenly tells you they are "honest?"
That's a huge red flag! I have had the same experience, in business, when people found it important to announce, shortly after we met, "I are a Christian". Then when something new comes up the they "have to pray on it". That only happened a few times and each time the "Christian" pretty blatantly attempted to rip me off or proved themselves to be degenerates.
Be wary. Just say, "You know, I'll use this online environment to get to know you and decide that for myself."
IMHO, this person is telling you what they want you to think about them. So, there's no way to know if its true or not. Online can be a very deceptive environment, so you have to factor that in.
