My husband is jealous of my son

My husband of 4 years seems to be jealous of my 12 year old son. Per the custody agreement with my former spouse, I have my son every weekend and all through the summer. He is now the only one at home; his other siblngs have moved out and on their own. When I pick up my son from school on on Fridays, we talk a lot about his week and just joke around with each other. My son is very intelligent has a wonderful personality and enjoys making people laugh. The problem is when the 3 of us are together, my husband is so quick to jump on every word my son says. He picks and picks at him and I have pointed it out & asked him to make an effort to try to make a better relationship with my son. My son now puts his head down when he sees my husband because he seems to know he is always being scrutenized. I try to engage each of them into mutual conversations, but as soon as I do, my husband spoils it by saying my son is out of line with his comments. He is twelve and I don't think his comments are out of line. I also should mention that my husband only had his son on the weekends per his divorce agreement & when we married & I had my 2 kids plus we acquired his, it was difficult because he had never been the custodial parent. Can you offer any guidance on this?

Do not spend time together all three of you. Encourage your son and your husband to engage in some common interest. Be wonderful to your husband when your son is not with you and ask him to engage in work or some other interest, when your son is around. Or do something outside the house with your son, if your husband likes to be home alone.
