Need advice about my Husband

I’ve been married going on 7 years we’ve been married since I was 17 and he was 18. We’ve had our ups and downs like every relationship but here recently my husband has been talking a lot about the fact that he could sleep with other women if he wanted to that he’s had plenty of chances in the 8 years we’ve been together. but then says that he’d never do that. He’s also said if I don’t give it up for a long period of time he has “the right” to go get it from someone else. But anyways I have a feeling this marriage is coming to an end and was wanting to know if anyone else’s husband says or said things like this or what you think about this.
