I will try to explain how both women deserve better. Respect,is very hard to get and so easy to lose especially the respect a man will give a woman, When a man dates someone exclusively he sends a message to the world saying hands off, this is my woman she completes me 360. If a man is dating multiple women at the same time he also sends a message, I am passing time, this is just a fling an easy lay. Trust me that is also a message to other men-to try your luck,neither woman is of that great a value to me -That is disrespect. But of the kind that only you can accept or not accept. lastly for space constraints, Most times if a man has multiple dating partners and they are aware of each other, it stands to reason that the women has the same rights to have multiple dating partners. unless that’s his thing, if a man tells you he do not care if you are seeing someone else. Run for the door, that man does not LOVE you. that is if you care that he does not love you or respects you. ( again we are speaking about the average male I am trying to be circumspect) because as doggish as men can be, they are just that possessive and most believe in the do as I say not as I do creed. Trust me, even in a pack,herd the alpha male have multiple partners but the female can mate with only one. it is so telling if a man is willing to piggy back behind someone else, you know what your purpose is in his life. Demand your respect and stand firm right around the corner there is another person just waiting and who knows, they may just be the right one. All women can do better by first respecting themselves and there is no man alive that is worth the price of a woman’s self respect. and that was the very circumspect version not going into the fringes and definitely not as colorful as when my mother spoke to me when I suspected my boyfriend was cheating ( yes I left the dog) and that is the gist of what I will tell my daughter with all the color and the fringes if and when I have kids, it is true sometimes mother knows best.
