Wtf did he do?!

So my ex husband left to his country for a few weeks. He told me there was some problems with his ID number being stolen from there and since we were still considered married in his country I would be responsible for him as well. So, we went to file divorce papers again from 3 yrs ago. I take him to the airport a week later, then two weeks later when he video chats the kids I notice a ring on his finger. I asked and he confirms that he got married. I am flared up. I know nothing of another person and neither our kids. I still loved him and he lied to me about the reason he left. I feel like an idiot and like he never loved me at all.😭 Believe it or not he asked me to pick him up from the airport on Tuesday. If this was you would you pick him up? I don’t know what to do. I’m very pissed and heartbroken. Help me please!
