This is very enlightening for me as a single mom of two boys. It is nice to hear what struggles and advice people have for the new partner. It must be intimidating at first. I admire your unique perspective in parenting. I must say, I found myself curious and a little threatened when I first heard that my ex had a partner. Now, though, my sons easily adapt to each environment as they learn the new person in their life. They laso have to figure out what the step parent likes, dislikes, how the step and original parent interact. Kids observe alot. Yes, they do adapt too. It will work.
