If you welcome someone else just after your divorce, it will likely only be a rebound. You are literally coming out of marriage, have a kid to take care of, so please take some time to think things through, what do you want in life, how you want things to be, and your way forward should not just be about having a companion. You want a father figure for your kid, so you need to understand what your kid's needs are, and then find those too in the other person.
Also, what @SpotlessReservation said is also right, when you want someone to be a father to your kid, and a partner to you, there is a strong chance that feelings would get developed between you both. I will request you to think about it. You don't want to tell the person to have a partner outside for their emotional and physical needs, only for you to backtrack on your own words in future. Explore a possibility of having a fulfilling relationship with them. What happened with your current partner shouldn't drive your outlook towards your life.
