My first husband told me after we were married for about a year that he wanted an open marriage. I did alot of reading, and you could say we "tried" it for awhile, but I was very reluctant. In my experience, an open marriage does not lead to greater intimacy between two people. It does take the element of dishonesty out, which is better than lying, however, the root problems are never addressed. In my first husband's case, he was a sex addict and had slept with over 20 women during our marriage and apparently had no intention to stop, so his idea was basically to stop lying and try to have an open marriage rather than fix his problem. I decided I wasn't up for that and agreed when he finally asked for a divorce after he "fell in love" with one of his play-pals.<P>Long story short, an open marriage is a cop-out. Your wife was not honest with you or herself before she married you. In my opinion, she is asking to have her cake and eat it too. She wants the appearance of normalcy and support for her children, but wants the thrills of being with women. Now, if this is something you can live with, or even "enjoy", then ok. The fact that you are posting here shows that you are having reservations though. You decide what you can live with. I think it is also perfectly acceptable that you insist your wife honor your wedding vows, and that includes faithfulness (yes sex with other women counts as infidelity!). Then it will be up to her to decide what she wants more, a life with you and the kids, or a life with another woman. Actually, like in my case, if this open relationship continues, it may only be a matter of time before she finds a woman she likes more than you. Or you find someone you like better than her. Really, it is only trouble for a marriage. It is much better to work on your marriage or simply get a divorce. There is less confusion for the kids that way and they don't end up with some twisted view of marriage (i.e. lots of partner swapping going on).
