Just seen on his apple

I grabbed the wrong Apple Watch this morning. Got a message and went to open up messages to check it while I was working. Ended up finding out it wasn’t my Apple Watch but my fiancés. Which, no big deal. I see a number that isn’t saved so I clicked on it, which was him saying hey. He has all his friends and family saved so I thought it was weird, looked it up and it’s a girl he somehow got her number. I thought he would change, which silly me… caught him cheating the whole time I was pregnant and part of after I gave birth. He said he would change.. I believed him. Our wedding is supposed to be in 6 days, with his family on our vacation.. we have a house, a 1.5 year old. I’m pregnant again and literally just found out baby never formed and I have to have a miscarriage either naturally or wait for my D&C after we get married. It is extremely traumatic and heartbreaking to say the least. Now I see this and I don’t think I’ve ever felt more alone, sad or broken in my life.
