Husband cheated at his bachelor party

We have been together for 7 years...we eloped this past year but are having a wedding with family and friends in Hawaii this upcoming October.

I am 7 months pregnant and have a 15 month old. He and I fit great together and I've supported him though everything. Right now he is unemployed and only taking 2 online classes but I know he isn't feeling great about himself so I've been letting him hunt, travel and train while I work 2 part time jobs from home. I have been paying for our wedding and most of the expenses.

He had a dual bachelor party planned in New Orleans for 5 days. He is there now. I woke up with our son at 3:30 because he was teething. I grabbed the iPad and started playing dog videos for him.

Meanwhile I saw this text come in. Some random girl telling him to stop kissing other girls and he replies "well you only live once and you're hot as shit" then said he hopes to see her again. He is there until Monday. I am alone and can't stop crying. It's 5am. What do I do? Do I confront him? Wait to see if he admits it? And then what?

He obviously wasn't too drunk to exchange numbers with this Ashley girl...

I never thought this would happen to me

First post on Reddit. Please help EDIT: first of all I want to thank everyone for the support and kind messages. I wrote this sleep deprived in the middle of the night. I know it's strangers but it was comforting to feel I have "someone " there.

His mom tipped him off that I know unfortunately and he wanted to talk on the phone. I exchanged some texts with him. He has all the typical excuses "I was drunk". "It was a mistake, I love you I promise I'll do better." Etc with more cliches.

I told him he is going to have to show me that he deserves to still be in my life, and I told him that he is not welcome home Monday night.

His mother blames "evil women" and bachelor parties. Must run in the family she said his father did this to her and she forgave the dad.

I have a JD and masters degree. When I want to pull the trigger and make good money I know I can. I'm still reeling from sadness and my self confidence took a hit.

Also...he has some of his own money that his parents give him from properties they gifted him. That's why he hasn't had a real job in 10 years or graduated school

EDIT 2: I just took the girls number off the phone and texted her. Told her I am not mad at her just need to know what happened so I can make the best decision for me and my children I

Edit 3: he is coming home early tomorrow. Though I will talk to him and confront him in person he will not be allowed to stay in our home. He can have his engagement ring back. Wedding is off. Starting tomorrow I will be working on recouping as much of the money as I can and putting it into a savings account for my son. Someday I'll take my kids to hawaii. Right now my priority is to get a financial cushion before baby 2 is born. Being in the delivery room is a privilege. He was considering missing the birth of this baby because his best friend is getting married 6 days after the due date. Well he. An go now.

Thank you to everyone who took the time to read and respond. I did not expect this many responses!

FINAL UPDATE: I gave him the ring back and said I'm not his wife anymore. We are separated and I'm trying to figure out everything. Thanks everyone for your responses!!! I did not expect so many people to care about a stranger. I most likely won't have time to keep checking back and might delete this in a few days
