You post this because you want someone to listen to you, not necessary an advice.
But, just for the sake that you know someone is reading and also cares here is my respond.
First dont get offended, when was the first time it happened na you were aware your husband is talking to his ex, when you are pregnant? Since the second awareness is during christening preparation na ng baby mo, i will just assume the jelousy is part of the hormones because of child bearing and birth.
Is the ex the person before you and before your husband married you? What was the story of your marriage and their ended relationship? Did they not have a mutual separation and were they not friends before your husband married you?
If they were already good friends before you two got married no need to freakout. If they just returning to talk to each other, accept and move on. Dont be too strict to your husband, it will give spark and excitment if they are doing something. And jealousy will burn your marriage to dust. If this is ok with you, You can talk to your husband the second time in a calmly matter that you are not comfortable with them talking to each other and just make one rule that he should not meet the ex without you even they will be with other people around. You can explain, this will make you feel at ease and this will be the basis of your trust and incase he breaks this rule you have something to feel outraged and jealous since the rule is not hard to follow.
If he also invites the ex, it is possible he is proud and wants to show the ex the family he is building.
Whatever we say in this topic it is really up to you
