He ruined my life.

So earlier today, my husband (M, 35) of 4 years revealed he's been cheating on me (M, 24) for 2 years. My life is wrecked. After all this time, all the things we've gone through, he just destroyed my trust all like that. We had adopted kids, and he's taken them to stay in his house until we can go to court. I just thought after dealing with his homophobic family, getting our dog Malvin, adopting children and then losing our dog Malvin, that he'd actually stick with me, but NO. He just goes around and screws me over. What do I even do? I have nothing anymore. My whole life was balanced on him and our relationship. I can't work for the kids, I wasn't the one with the job. I cooked food and did the chores. It's over for me. Any advice? I feel like it's over.
