<human>: Provide a brief overview of the text.

Excuse my format I'm on mobile. 

Me and my husband have been together for five years and married for three. Before we got Married we had an understanding and agreement of an open marriage. He has had several girlfriends they have come and gone and I'm ok with this. He is currently only talking to me.

I do have a FWB. We'll call him Jesse. Me and Jesse get along swimmingly. I loving having sex with Jesse... a lot. He may even be the best sex partner I've ever had. I don't love him but I do love the sex. He and I both know this.

Recently, about two weeks ago my husband expressed his concern about closing the marriage. I didn't agree. I'm enjoying myself and frankly loving having my cake and eating it too. I did listen to his concerns. He doesn't like me with Jesse and has developed jealousy. 

I tried addressing his feelings but I did't want mine to be ignored. We were supposed to continue the conversation last night but it didn't go so well. 

My husband is accusing me of cheating because I have slept with Jesse since our last conversation and is demanding that I break up with him. He called Jesse and threatened to sterilize him. I don't feel like I've done anything wrong.
<bot>: My husband and I had an open marriage  he decided he doesn't want that anymore. Now claims I'm a cheater.
