What would you do?

I found out last night he has been cheating … he begged me to go over and he spent an hour in the RR before actually getting in the shower and when he was done he stood in front of the tv on his phone as if he were so into the movie… he laid next to me and I could feel it in my bones something was up so I just waited until we were both sound asleep I knew I’d wake up while he was snoring and I couldn’t help but check his phone of course he left it near the tv while he slept… I opened it and he left it open on Snapchat ofc that would be the first place I’d check… he was messaging a female that entire time he was in the RR… I scrolled seen a bunch of Ily texts and how he couldn’t wait to spend the whole day with her and how he wouldn’t know what to do if she’d left him.. and ofc lots and lots of explicit and vulgar messages and pictures… he was sending and receiving… all the nights he “fell asleep” he was talking to her … All the times he “forgot to reply” he was talking to her … it’s sad because I actually believed every word he said to me but he said the same thing to a complete stranger… he “loved” me because he was alone… the worst part is she’s from Germany… she’s across the whole sea!!! And he chose her over me … I was pacing back and forth trying to figure out what to do cause he had picked me up and I didn’t have my car … I continuously got up to go pee and vomit I was soooo sick to my stomach… the last time the toilet was still running after I had flushed he got up kissed my forehead and turned it off… came back and put his head at the bottom of the bed and wrapped his arm around me.., I felt DISGUSTING… he asked what’s wrong and I said nothing .. he asked again and again until I finally got fed up and I said “what would you do if you found out I’m cheating?while I’m pregnant ?” I asked this 3xs and each time he said IDK … I turned over and something came over me I got up put on my shoes grabbed my purse and said take me home YOURE THE CHEATER… YOURE CHEATING ON ME !!… he got up and walked out the door behind me.. I got in the backseat and I just started questioning him over and over … he told me “idk what to say” The entire way I was just pouring my heart out and he had ABSOLUTELY NOTHING TO SAY… I decided to text the girl… She knew nothing about me I asked how and where they met she said “a game” Continuously apologized… And when I got home I got in my car and went 120 on the highway I drove until I got to corpus, I didn’t know what to think or do .. he didn’t text or call crickets I texted the girl and asked if he’d apologized she said he did … and that broke me .., if I weren’t already broken before …he then texted me … only because she was otp with him and he had nothing to say for himself… nothing at all … I called and went off and added her to the call … he hung up … I asked him why over and over.. and finally he said “I can’t help that I have feelings for her” then “what do you want me to say I’m falling out of love with you” I told him “F YOU!” I want nothing to do with you and you don’t have to worry about me or this baby don’t call text or contact me in any way… I then told his sister.. EVERYTHING she replied hours later because she was sleeping saying how sorry she is and how mad she is with him and how I don’t deserve this… also told me how she her parents and the rest of his family would be there for me regardless.. I really appreciated that because they don’t have to be … it’s been hours and he hasn’t tried contacting me .. lol he is in love with a woman (well she looks pretty young if you ask me )he will probably never meet and I am so heartbroken he threatens that he will take me to court if I try and keep the baby from him… but I truly want nothing to do with him..
