STOP. Because you know you need to stop. You are wise. This is an internet hook up. No one needs to know where you work, life or any such thing. The fact that you are questioning this person is evidence that you know it is going down the wrong path. NO ONE talks video chat daily. No one talks that long either. Husband and wives don"t. Grandma's and grandkids don't. They have lives. Gardens to weed. Walks to take. Painting to paint and dogs to feeeeeeeeed. Do you work? Do you read? What else could you be doing?
You know what to do. Take care of yourself. Watch out.
