I let her take advantage of me sometimes. Everything was mine before we were married. The homes, cars, money were all mine. She doesn't even have access to my bank accounts or credit cards.
I let her stay in the house because we've been together so long. I trust her, and I know where she is when she's not here. I don't want to be a total douche and put her out on the street while she's still kind of fucked in the head.
