Been there. Done that. I trusted my ex when she went out with her friends. One of them covered for her by doing a call forward to make it seem like she was at her house. I never cheated, but had s part in what destroyed our marriage, but it still did not make what she did right. I tried for quite a while to mend the relationship. That was fruitless. I was the only father my stepson knew. He was 1 1/2 when we met. We had our son 3 years later and within a year (or less) she was going out all the time, while I stayed home to be with my boys. This was after me working for 10 or more hours a day. I look back now and wonder why I even put in a losing effort to restore our marriage. My stepson and son lives mainly with me for years. She lived her partying life. When my stepson was 12 he started ditching school, got caught with a knife at school while showing it to his friends. He ditched like 3 times in a week so naturally we got called into the office. I explained to him why this needed to stop. Then the next week we got called in for the knife offense. He then got moved to his mom's while I still had my son. Since then she has had multiple partners. Multiple residences, because she was always getting kicked out. My stepson got into drugs, dropped out of school at 14, and is now on heroin at 19. My son is doing good in school and is an awesome kid. Not just my opinion. Been told by his friends parents and teachers. Her lifestyle sent my stepson on a bad path, because she had no time to be a real mom. I feel your pain. I'm just glad I didn't have to live in the same house as her.

I say all that to tell you you're not alone and to make sure your kids are the first priority. Get a lawyer and figure out how you can split the assets, and settle the custody. Move on. The fight to win her back is over. Don't lose a couple of years of your young life pining for a liar and cheater. Her and Brian deserve each other. It will end badly for both of them. Just don't let it destroy the kids and you in the process. Sorry for your situation.
