Husband and guy friend

I dont know what to do.. here is a little background story. .sorry is long.. . So the beginning of this year we became friends with a guy and his wife. All of the sudden they wanted to go out all the time with us, I was getting tired because we never have time for ourselves anymore (we have a 3 month old daughter) and it was always hanging out with them every single weekend, not family time anymore.. They both love fishing, so it has been times where my husband changes his night off (3rd shift job) so he could go fishing and then work the next available night... sooo this guy is ALWAYS texting my husband either at 6 am through 11 pm, I have read some messages where he is asking if he can call my husband and if my husband is busy and doesn't answer, the guy told him it was because he was with the witch (referring to me).. and also found that on whatsapp he has send my husband pictures of girls with booty shorts or naked and ask him if they are hot or if he will fuck them.. my husband replied with oh yes I will, they hot, and awh look at that booty. I feel disgusted of how my husband is becoming a new person since this guy came into our lives, also how he let that guy talked about me like that..i don't know what to think or do. My SO answer his messages so fast and when I send him a message he will take a long ass time. I'm desperate, I also need time for myself but I'm always with my baby, while my husband can go out all the damn time... Sometimes I feel that he is not paying me attention because my body has changed, I feel ugly, I don't feel attracted anymore..

How would you girls handle the situation ?? Or what would you girls do ???
