Ending Relationship

So for those of you that don’t know, my boyfriend and I are in an open relationship and I am actually thinking about talking to him about ending it and keeping it monogamous. Being in an open relationship gets tiring and boring after a while, although it’s nice to be in a relationship and still have freedom, there’s too many things to keep track of. I also don’t want my daughters to want to be like me and have the same type of relationship that I have with all of these men. I hope my boyfriend is on the same page as me, especially since we basically have a family. Any advice ladies?
