Found out my husband has been cheating (sorry for long post)

Hi guys...I feel so silly typing this...but I’m so heartbroken and I have no one to talk to. I’m literally in tears as I’m typing...this evening I caught my husband cheating and I was totally blindsided. We were sitting out on our patio having drinks listening to music, laughing and talking and he asked me to give him a back rub. So he came and sat between my legs and almost instantly his phone rang and it was one of his very close cousins but the name came up different bc it had his last name and it never comes up that way. He rejected the call and I instantly knew something was off. I asked him why he didn’t answer and I told him to call him back. I’m never the insecure type but I just felt in my gut that something wasn’t right bc I know for a fact that’s not how the contact is listed in his phone. And the more he resisted calling back the more I knew something wasn’t right. So I just grabbed the phone and saw the same person had just sent him a text which said “I need some dick baby” He pretended to be so shocked saying they must’ve text the wrong person...which made no sense bc the number is saved in the phone and i know damn well your cousin isn’t texting you asking for dick! So i texted the number back and asked “where are you” and they responded “heading to work but I need to see you when I get off.” I think the reason he didn’t grab the phone is bc there was no next thread for this person prior to that message so he figured I wouldn’t find anything...he didn’t see me texting back bc the whole time he was still sitting in front of me. Then I called the number. Of course a woman answered and I put it on speaker. She said “hey baby” he proceeds to ask her who she is and how she got this number. At first she was confused like duh this is me what do you mean..then she started trying to play it off saying she must’ve have texted the wrong person once she caught on to what was going on. After that i hung up the phone and I told him to get all of his things and leave. He resisted, begged me to believe him, cried, blah blah blah...but one thing I’m not is a fool. I’m also very spiritual and I know that all happened exactly like that for a reason. I never go through his phone and up until today I did trust him. He has cheated when we were dating but one thing he’s always been super serious about is marriage. He didn’t have a good family growing up so having a real family was supposedly something he held in very high regard, so I honestly didn’t think he would cheat...we are still newlyweds . But anyway after hours of arguing, he finally packed all of his things and left. I told him not to come back and not to contact me. We do have a small child so at some point we will have to figure that out but for now I just want to be left alone. Cheating is a deal breaker for me, so there’s no fixing this and I’m not just saying that out of anger I mean it and I will stand by that no matter how bad it hurts. But although I’m sure of my decision it just hurts like hell. I have a pain in the pit of my stomach and my heart just hurts so bad. I can’t even put into words how sick I feel then my baby is looking for him... I’m a tough girl and I will bounce back but right now I’m hurting so bad and just need some encouragement. Sorry so long and please forgive any typos....I’m typing through my tears. Please pray for me to have the strength to get through this

Thank you ladies for the kind words. I truly appreciate it
