Is this a weird fetish?

Just wondering if this was a thing. My husband and I have been dating since we were 15. We've been together for 9 years now, married 3. We've been trying for about a year and a half. After going to the dr, she prescribed me medicine, been taking vitamins, and just trying to do what everyone says and enjoy making a baby. I decided to do something a little different this month and have sex every night. Hey, it worked for some people, and I mean it never hurts to just try. So it seems as some times when you try to prevent it, it happens. We decided to pretend to each other, before bed, that we were seperated. In the middle of a divorce, and he was moving out soon...kind of like role playing I guess. I'll ask him to wear a condom, he'll say he doesn't like them and that he'll pull out, but he never does. He kind of acts like he still wants to be together, but I think he needs to change. And he wants me to keep his last name and once it's finalized he's gonna continue to pay the bills, but I can't be with anyone but him, and he can be with who he wants. Sounds crazy right, but don't judge sometimes you gotta spice things up and were looking into each other for that. Idk, I know divorce is a painful thing, and I don't want to step on anyone's toes, but I've always wanted a fwb, and now I can have one and a husband at the same time. I know that sounds kind of contradictory and cancels each other out, but well it works.
