I must say, I am so relieved! I took dear Polly's comments and acted on them by having a few words with my son. I told him that I feel better about his moving out to rent a room and to explore adulthood on his own. I explained to him how I've been thinking about it and I have come to understand where he's coming from and what he feels he must do.
I was sincere when I spoke with him. I told all my kids that there comes time when they get that "itch" to be on their own. It's nothing personal towards us as parents....hmmm I have to think about that a little bit. My point is, I do understand that "feeling" of wanting to be on their own. I fully support them. Yes, for mom, it is bitter-sweet. They are our babies. It doesn't matter how grown up they become, they are still our babies. It is just as much of a transition for us as it is for them.
So, with that said, he took me over to his place ("room") where I met the owners of the house (their daughter is renting a room as well, with one other house mate). It is very clean and I like the neighborhood. I helped him move and bought his first set of groceries. The transition was easier than I thought. He knows he is welcome to return home should anything go wrong...this is not a "permanent" offer...lol!
