Welcome to our forum.
Have you talked with your husband about the possibility of him taking another wife? Do you know what his feelings are about that?
There is a lot of good reading material here on this site, so hopefully some of that will help. Don't hesitate to post any thoughts or questions you may have.
Every family is different, and only you can know what's right for you and yours. Sure a second wife could turn out to be a problem person, but that's the nature of love; it is always a risk.
Glad you could join us, hope you enjoy your time here.
Love means never having to say, "Put down that meat cleaver!"
