I'm so glad you shared this, dear! I am too in the same situation. Jumped into a relationship as of August. So that's about 5 ish months since I left my exA. My new guy is not an alcoholic, but the transition to the relationship is a hard one. Having had a great foundation of recovery when I was with my ex and on my own has helped tremendously in my new current relationship.
I have nothing but great things to say about my guy and his sweet daughter as well. What's helped me is the communication. I tell him about my deep flaws of "insanity" and how my brain works. I work my program and he actually helps ease my mind at times.
One day at a time- this is great news!
