I merged your threads, Mahogany and Bo. And yes, please do make yourself your own account. It gets very confusing otherwise.
I think you need to sit down and be with us for a while. There is a lot to read here, even if you decide not to write anymore.
You don't seem to know anything about polyamory. First of all, the language: your wife, you might consider calling a "primary" partner, and your girlfriend, a "secondary."
I won't go into details about all that, but if you look at the definitions thread in the stickies at the top of the "new to polyamory" main page, you will find a whole bunch of useful words to use in order to explain what is going on for you, to us, and each other. That way all of us will be on the same page.
9They are useful words for newbies. Often, with time, people abandon some of their meanings for something that fits better for them. Baby steps with all that, though.)
Take a look at those who have gone before and realize that you are not alone and poly can be and is achievable.
May I suggest looking at these two threads first?

It seems that you have some stuff to sort out for us, if you will. I am very confused about the dynamic you have, and perhaps others are confused too. From the thread Mahogany has posted, is it possible to take some ideas about what you might comment on, to bring us up to speed about what is going on for you both?
Thank you for sharing something so raw with us here. I always find people's ability to make themselves vulnerable to strangers incredibly honouring. Thanks for trusting us and reaching out.
*hugs* to both of you.
