I feel so jealous right now 😞

So my husband and his ex girlfriend are just now getting to the point of wanting to baptize their daughter, well she absolutely hates and she acts like she hates him. I told him it would be confusing for their daughter of they took pictures of all 3 of them and he agrees, 
Has anyone else just felt jealous and insecure even though they are the wife? Not everyone knows we're married since we eloped back in March and I just don't want pictures posted online and then people think they are either still together or got back together 😔
