They Begin To Want An Open Relationship
Open relationship equals cheating without feeling guilty about it. If they come up with this proposition to you then break up right away. In their mind, they want to meet people on the side and want to engage in sexual escapades.
Meanwhile, you sit at home by yourself and cannot find a person with whom you can spend quality time with. It really is a bad place to be in. At first, the prospect that you will finally have threesomes is great, but the reality is much worse. They will start bringing strangers into the house while you go about your work.
Sometimes you feel hopeful about joining them but when you do it is usually with more people of the same sex as you and that is not so exciting. It is really bad especially if you have children, they could grow up as disturbed as their parents.
