Hello and welcome!
You are taking the most important steps. Alanon and Therapy. Make sure you are being 100% open and transparent in therapy so you can recognize and avoid old patterns.
I have taken a hard stance myself. I don't date anyone who drinks, at all. Nor would I date anyone in recovery. It sounds harsh, but I would rather be alone than risk going down that road again. That is a personal choice for everyone, and not everyone will agree with me.
Keep working on YOU!!!
