I will have to add to this thread.
I had already been married for 10 years when LR told me about her being Poly. I thought I was going to die a horrible death by being burned from the inside out. We were married we have kids and I love her. Even with all those things going for us learning to " BE " poly is the hardest thing that Ive had to do in all of my life so far.
To be honest I dont know if I would have got married to her had I known back then. But I did marry her I do love her and I began the long hard journey of self loving.
My biggest piece of advice for you is , dont confuse things by gettign married and having kids. Deal with your inner demons ( insecurities, jealousy ) first.
Peace and Love
