where do I start?

I don't even know where to start here.
Ron moved back in today. The people he was staying with have kicked him out. I know that no mater where he is staying for the moment that it is only a matter of time for them to kick him out and him to come crawling back to me with his little 'mommy' cry. It's very irritating that he is 5 years older than me, and my ex boyfriend... and yet I've ALWAYS been the one to take care of him... I'm always the one to comfort him. How do you tell someone you love 'Oh well, so sorry you're homeless.' and move on? I can't. Of course I had a choice. We're all given choices in life. And so I made the only choice that I could make... based upon the "What Would Jesus Do?" mantra. So he's here. And he's promised me that "this time it will be different..." and even though I don't believe that it will be any different than the past several times that he's moved in with me and used me... I still welcome him with open arms.
