My husband of 2 months already wants a divorce ...UPDATE UPDATE

I’ve only been married for 2 months, I have 5 children from previous relationship and he has one....my relationship was always great, it was perfect...until a month ago things took a turn for the worst, it started to get rocky. We decided to take a camping trip this past Memorial Day weekend and it completely turned into bs...he was complaining about me and my kids the whole time (mind you I only brought 2 of my kids with us on this trip) being so rude about them talking badly about all of us...when we got home we had another argument and he wasted no time, packed his shit and left....I’m just completely heartbroken and devastated. I just need some support. 😕😒....below is screenshots of the argument at camp

Update: so to clear the air about a few things mentioned in the comments section, we were together a year and got married 2 months ago....we can’t get an annulment because you can only do one if the marriage was under false pretenses (someone was already married or lied about something significant that voids the marriage) he lived with me since February and he’s definitely spent a lot a lot of time with my kids before we got married ...he used to be AWESOME with my kids it’s actually what sold me about him, I have countless pics/videos of him being a great father figure to my kids. He obviously flipped a switch super recently. He says in the texts that my kids break everything and aren’t disciplined but that’s really not the case my kids are a little crazy sometimes but nothing of his has been broken except a fishing pole (which I gladly offered to pay back) he used that excuse to obviously keep my money...I gave him 4000$ to save for me (we were saving to get another house) I trusted him with the money but I had no access to it...I asked him to allow me access to the money saved up and he refused mind you this was all my money saved up he didn’t add or contribute to it...he was also “breaking up” with me every week and telling me he won’t give the money back because I have to pay for him to get a new place since it’s my fault he has to get a new place to begin with...this is only the tip of the ice and of course there are two sides to the story, I tried my best to tell his side too...I knew it was a lot for him to handle 5 kids, and I am not perfect...its been over a week and I still haven’t heard from him at all so I guess this is it....thanks for all the comments and opinions

Update: so yesterday I just found out that he was cheating on me with some girl, she came to my house while I was at work and helped him move his belongings out!!! And he started taking to her a week into switching jobs that was about a month ago which explains why he had an attitude with me during camping so he could have a reason to bounce when we got back. He also hid the fact that we were in a marriage on Facebook and made it so that no one could see anything I tagged him in. I thought those were all red flags. The girls sister reached out to me and told me everything...oh and PS....he told everyone I was trying to trap him with a baby to get pregnant when were TRYING for one together. 🤣🤣 today I went and changed the locks on my doors and he’s not getting anything until he pays me back the money he stole from me.
