Why am I so insecure

Elexis

I’m married to my best friend, we talk on FaceTime all the till he goes to work at night. We live cross country till the second week of may I finally get to move. Lately I’ve notice him liking girls who are skinny and large chested and big behinds half naked pictures. Not often maybe once or twice a week. They aren’t local girls to his area and basically “IG Model” every time I see him liking a pic of them being half naked o get so sad cause I’m going to get bigger and ugly. I’m going to be 14wks pregnant with our first together. He says they mean nothing and that I should know I’m his one and only. Everyday he flirts with me as if we were first dating and calling me his beautiful pregnant mermaid. He always makes sure I’m ok and makes a effort to make sure I feel beautiful. But those girls are so beautiful and have way more body then I do. This is me in a picture with him I love him so much and never once has he made me cry ever. But I’m just so insecure. I know I’m ranting. But I needed someone to tell this too besides him.
