Cheating husband not clickbait

So long story short.. little over a month ago.. I caught him. Id found his messages Sexting with another woman. I haven’t let him know I found out. I went blank. I went numb. When he was at the gym later that same night that’s when I let out my crying and screaming because I wanted to collect myself so I didn’t do something I’d regret.. I am at this point after doing a lot of thinking.. considering not telling him and continuing to let him think everything is normal. Like I have been the last month. I was a stay at home mom for the most part before (I only worked 2-3 days a week because we don’t have child care for our TWO children) so I started to slowly put money into a secret bank account only in my name.. I’m considering keeping that up. Slowly moving money into MY account While I work on things like my credit and finding decent prices for apartments and childcare and programs that maybe could help me if needed then when the day comes that I finally have myself on my feet I will just... leave. I will get an attorney and give him the proof of cheating that I saved because obviously I was going to save it.. and let my attorney do the talking. I mean I don’t feel I owe him an explanation.. I don’t feel I owe this man shit to be honest.. I don’t want to tell him I know what he did. I don’t want to tell him I want to leave. Why should I give him that information in advance when because of this virus I have no means to leave right now anyway? I also have no family. I’m not being dramatic I genuinely mean I have no family. My parents didn’t have siblings not many cousins. They didn’t associate with them. I have no cousins uncles aunts nothing I’ve grown up with. And I don’t associate with my parents because they did some things that are too much for this post.. that’s another story..

My question is: is keeping my planning a secret until I’m more stable a good idea.. or do I have to say anything right now about what I know and what I plan to do.. I want to be thinking clearly. I fully believe in trying to work through things however I know I will not be able to look at him again without seeing her. Replaying what I found. I could just use some advice.. I have no one to talk to and I refuse to let my boys (4 and 1) see their mama break.

Edit:: I just want to say thank you to those who have encouraged me during this time but I also want to address those who said I should think about it first or maybe try to work it out- no ma’am. Thank you, if that’s what you would do then good for you but I do not tolerate cheating. I am his wife. I am the mother of his children. His loyalty should have been with me. Not some random woman he wanted to get temporary pleasure from. There is no discussing that. I would NEVER be able to trust him again. How would that be fair to me or him? For me to be always asking where he is going and who he is talking to because ultimately that’s how we’d be because I wouldn’t trust him anymore. The life I lived before I found out was just fine but nothing I’m not willing to give up because I can give that same life to my boys without him 🤷🏻‍♀️ I do not need him for that. This divorce IS his fault. Not mine. That’s just how I feel. I will step up and be the best for my boys and I will be strong. If God has a man out there for me then he’ll find us one day but it isn’t a man who lies and cheats. I know I deserve better and I’m not letting dishonesty slide. I meant my vows but he didn’t. He broke the promises he made me and now I set him free. I love him. I always will but I am no longer in love with a man who puts me second. I am NO ONES second choice because they want a girl here and there for a good time for a short time.

Thank you all for the words of advice. I am leaving him. Bottom line. I am going to do what needs to be done, credit, accounts, my car etc and I will be leaving once I’m on my feet enough. Much love xoxo AnonymousWife
