This is going to be a little long because I have to explain everything since the beginning.

Back in July/June I found out that my husband was texting his ex girlfriend, the one before me. She asked him for his number and everything. I told him about that conversation and he told me it was nothing, they “stopped” talking. Fast forward to October when I see that HE called her on his birthday through video chat, they talked for a good few minutes, that they he left early for work (he works sometimes at night) and apparently forgot to delete that conversation. The next day I tell him about it and he said that it was because it was for his birthday and that it lasted so long because she was asking him about his married life and the new baby. Ok, I left it there, a week later he gives me his phone because I needed to use the gps for work so he left me his phone for the day, I see that she sent him a picture of her in the hospital BUT I don’t see a conversation because I think that he deleted it but forgot to delete the picture that was saved from his whatsapp. I say nothing, I keep quiet, two or three days later she posts something (talk to me, I haven’t heard from you in days and I’m worried) she added his initials it WASNT direct message but it was a status. I said nothing kept quiet BUT I did take pictures of all from my phone I also told my baby sister to add his WhatsApp on her computer so she’d get his texts, I gave him his phone and the next day after work he sent her a voicemail asking her how she was and stuff, idk what happened but I think that he was trying to call her but he didn’t have good signal because she asked him if he could try again, my sister forwarded me all of that and I KEPT IT, ANYWAYS. A few days ago an old neighbor of mine had his birthday and I sent him a message saying “happy birthday 🎂🎁” he said “thank you love” THATS IT, I didn’t even read it. He had my phone and read the convo when I came home from work he started talking and even asked me for a separation called his mother and told me that if I wanted the divorce, he was sooooo mad and almost crying, telling me how I’ve been disrespecting him and stuff he was going to give it to me. Then I came with all the receipts BUT I never showed him the voicemails only the pictures and stuff, after him saying that she was sick and only tried to show him how she was. I showed him the voicemails and kept quiet, said nothing and went to work.

We’ve been doing so good when it comes to the baby, we only talk when it comes to her, he sleeps in another bedroom but comes to mine when it’s his turn to take care of her while I’m working.

Today he left me his phone again and something told me to go to his emails, it never crossed my mind before so I go to trash and guess what? He forwarded pictures of his ex, NUDES, even pictures of them together (not naked) only together, she sent him selfies too so it’s on his emails trash but forwarded to himself, they were recent like on his birthday, from July /June I took pictures and have them saved, I’m not going to say anything until I can. But I don’t know what to do should I ask her anything or him or just keep quiet? Please help

EDIT

THEY DONT HAVE A KID TOGETHER when I said that she asked him about the bay was my husbands and I, that’s his first kid. They’re just ex’s.
