Is my husband cheating???

Okay so I’ve been married for 5 years now and we just had our third child 6 months ago. During the pandemic in 2020, I found out that my husband cheated on me. The girl he cheated with found me on social media and sent me evidence of their affair and other women he was communicating with. I gave him plenty of times to tell me but he never confessed until I had a lawyer call him to inform him I was filing for a divorce ( all this happened while pregnant, but didn’t know until I was already 3 months). Even after receiving the call he still acted like he didn’t know why I was divorcing him. When I finally told him all that I knew he just got quiet and apologized. We spent some time apart but not long enough for me to fully heal from the trauma. I decided to forgive him and work on our marriage. To fast forward we agreed that I stay home for 6 months after having the baby and return back to work, then he suggested I stay out the rest of the year and return to work Jan of 2022. I mean it works out for the kids and him since we only have one car. But he’s always hiding his phone. He’s gets texts early in the morning. He even puts his phone on airplane mode when he sleeps. When I confronted him he said he didn’t want anyone interrupting his sleep. I’m always home and don’t have any income coming in. I’m currently finishing up my bachelors degree and always have to fuss for him to give me money for house supplies or things for our kids. He’s always so busy since he works 2 full time jobs to pay the bills and we never go any where even on his days off. He’s always glued to his phone from the time he wakes up until he goes to bed. He hardly spend la quality time with the kids. He acts annoyed with them sometimes and I explain that they hardly see him and just wanted his attention and affection. He never makes plans with me or with our family. He constantly leaves out multiple times at night but doesn’t stay out long. Always “taking trip me to get a drink or a snack or a cig” Every time I confront him about cheating he denies and says he’s too busy to worry about that stuff. I want to believe him but idk since he couldn’t tell me himself that he cheated on me and didn’t confess until I had him cornered (figuratively). I’m thinking about just getting a divorce soon since I don’t feel like I’ll ever be able to trust him. Plus he has a history of having issues with other women as far as talking to them. If I even get a like from an ex on social media it’s a war. I’m not sure what I am asking but any suggestions on either moving past this and continuing my marriage or could he possibly be cheating / communicating with other females and I should just leave?
