Peggy,
we have all been there, we r all enablers. But you realize this now. The work for you know is how to overcome this and not do it again. You need to keep reading, and educating hourself. Addicts groom their enablers to get what they need, we need to recognize this and work on our short comings.
Hit an alanon meeting, hit the new to recovery and alcoholism forum. If you don't learn what not to do, you will always be an enabler!!
Hugs my friend and welcome to the club, that no one wants to belong too.
