@Have Hope I think one thing you need to focus on is your husband's addiction to the internet and to porn.

Since your husband used it before in his first marriage, there's no guarantee he's not hiding it from you right now. Do you know if he's on that Star Wars game or is it a porn site, when he's always on his phone?

What does he spend his money on -- like that $150 he spent using your credit card. His addiction to the internet should be a major concern for you. That he can't put his phone down when he should be focused on spending time with you, is concerning.

There's something called IA - "Internet Addiction." I found a study about it. It includes porn addiction in it too. Neuroscience of Internet Pornography Addiction: A Review and Update

There are 3 stage of Internet Addiction:

Stage 1: Binge/Intoxication
Stage 2: Withdrawl/Negative Effect
Stage 3: PreOccupation/Anticipation

I think you may want to separate your finances from your husband. You could always set up a 3rd account where you each "pool" some of your own money together to use for bills or groceries. But I definitely think he's hiding something from you, based on the behavior you describe with his phone addiction and his previous use of porn during his first marriage.
