M.P.
Hello N.,
It does not sound to me as though you are really ready to do this.
I am a mother of five, who all slept with me at one time. They don't anymore so it does come to a hault. When I was around your age I read a wonderful book called The Family Bed. In there it told of other cultures that we might consider primative who actually had a much healthier view of families who sleep together. I am a writer and I once did an artile on the family bed. It seemed to dispel a lot of worries for young couples.
The Native Americans, whom I hold near and dear to my heard lived in very small quarters sleeping together. They had stronger family bonds.
You have been given a wonderful gift of mommy intituition. Follow that. When you expressed a concern about the spilt plan of your house, your concern is not without validation. You and your son will know when it is time to make the spilt. Your bed is a safe haven for him.
I always knew when my teenager needed help. I would find them alseep on my bed when coming home at night. this was an indication that they needed to talk. they knew that 'going home' they would find comfort.
Hope this helps.
M.
