Hi there and welcome! It sounds like you have quite the happy poly tangle there!
I'm sorry about your recent loss. It's probably a good idea, to help you in the grieving process, to spend some time here sharing your experiences with other poly peeps and newbies. You sound very balanced and content with your situation, and I'm looking forward to reading more of your posts.
PS - We also have a weight loss support
thread in the Fireplace section. I have quite a few lbs to lose, and there's a bunch of us who I'm sure would love to hear what worked for you.
