Insacure

So I'm gaining more weight and losing my shape more in this pregnancy (2nd one) and with being sick all the time and my hormones. I'm more insacure. So I'm getting a little jealous. How do you deal with it ? My husband and I were talking and he talked about his friend had this girlfriend and that he was an average Joe and she looked like a model. But with such emphasis and wouldn't stop saying it. On how beautiful she was. I got a little irritated and got quiet. Because first off I know I'm no model but he never got that excited and emphasized with me. I get there's always going to be someone more good looking, etc. But I'm just emotional. How do you guys deal with it ?
