Thank you for writing to us. The easiest way I can convey what I am about to say is that it is time to move on.
Open relationships do not work. It is as simple as that. They have limited value as a transitional stance, but ultimately the very human factors of security, intimacy, and self-esteem eclipse the transitional stance. If they work at all it is because they prevent deeper intimacy, not promote it. For those who want to keep intimacy at bay an open relationship will do the trick.
That having been said, your relationship does not sound truly open. You have not mentioned your side of the equation. If he is having sex with other women, are you having sex with other men? If not, why not? If it is because you are hoping to be faithful and that he will eventually curtail his other relationships, history would dictate you are wasting your time.
He doesn’t sound like relationship material. If intimacy is what you are looking for, find a person who is willing to be connected to you in a way that mirrors how you are connected to him. If you haven’t tried some individual counseling, you can use our find help tab at the top of the page to find someone in your area.
