Does my boyfriends father have a crush on me?

Anonymous
So me and my boyfriend have been together for 5 years and have known each other since we were 10. And I've noticed as of late his dad's been acting a little flirty with me. He constantly compliments me, telling me I'm beautiful and I'm gorgeous and that' I'm an amazing girl and that he love his son but I deserve a lot better. He jokes about me having a big butt or calls me bubble butt. He constantly trys to wrap his arms around my waist and my back. He's constantly messing with me by telling me we should move to another state and start our own business together. Or that we should build our own house for only me and him. And he also tells me every single problem him and his wife are having and how if she doesn't stop he's going to leave her. He tells everyone he sees me as a daughter but then does all that stuff when it's just me and him around. I'm so confused
