Hiya Babyblue,
It really depends on the person how they come out of rehab, sorry. Some come out of rehab very happy and recharged, and ready to start a new life.
Some come out of rehab and still think it's all about them, which it is in a way but everything might revolve around meetings and AA for awhile, which is good and sometimes bad.
Just remember you are 50% of the relationship and deserve 50% of the love and attention.
You are very supportive and you seem like a great woman (remember we are the smarter gender, j/k, or am I?)
