(Long post) caught my husband with another woman

Ru
I'm 17 weeks and 3 days and my hisband and I both work at the same plant but he's a Supervisor and I'm a QA and I've been noticing him leaving for 30 min or more every night this week and I would ask him about it and he would lie and say he drove to the other side of the building and was doing work over there. But he would never answer when called on the radio and he would turn off his phone during this time. Well this Tuesday or Wednesday night, his lead was looking for him and Again I called him and his phone was off and she mentioned another girl was missing as well. Another worker called her and her phone was off as well. They both ended up showing up at the same time and I asked him where he was that everyone was looking for him. He didn't answer just said he was in receiving again. But then I asked him if the missing girl had been with him and he exploded saying that I didn't trust him and he didnt want to be with me and that it was over. We've been married for 6 years together for 7. I gave him his space but I still cooked for him and brought him lunch and held hands while we slept and told him I love him every day. Since we can't kiss at work I would ask him to give me a hug and kiss every day before he leaves. And he would get mad and say stop im done with you. And I would say no we're married and I love you no matter what. Anyways yesterday I didn't bring lunch but I was going out to get us some burger king since it was pay day. I noticed his vehicle missing and called him to ask if he had already eaten. No answer as I was leaving I saw him coming back with another girl is his passenger seat. As soon as he saw me he turned around and drove crazy through town to try to lose me. He even crashed into me hoping it would stop or slow me down. I followed him and he dropped her off at her house. The other girl works with us too and my husband is her Supervisor. She was to returm to work but since I caught them she hid at that house to no face me. My husband not once asked me if I was okay he told me to leave him alone that he was done with me. And I said we're still married and he ignored me and walked into work. Idk what to do, i feel so stupid. And that girl is married too and has a baby with another guy. I knew something was up when my husband would turn down sex. I love him so much and I told my friends I love him so much that I would still take him back if he truly came back and tried to fix things I would take him back. but I know he never will....
