If you feel this way, I would say follow your instinct rather than taking a risk. Otherwise, my opinion is that it depends on many factors: yourself and your general condition/mental health, same for the other person, and just what your goals are in sobriety. If you have a lot of things in your life that need attention and fixing, or that you want to work on with a lot of energy, I would not recommend a new relationship for a while, prioritize the most important issues. I also would not recommend a relationship with someone who has personal / emotional issues that could cause stress for you.
What I usually suggest to people here: why not just be friends for a while if you have doubts? You don't need to put a name on it. Get to know each-other, do things together etc without anything serious, see how you feel. If he is really supportive and understanding, he may not want to rush it for you.
