28 weeks pregnant and devastated

I feel completely broken beyond belief betrayed and just so confused my boyfriend of two years had mentioned a trip to greece for a college semester to me way back in March I told him I wasn’t comfortable with it and I made him promise me he wasn’t going to go and leave me I realize now that was very selfish and wrong of me to do but we found out I was pregnant about two weeks after he mentioned it I made him reassure me once we found out that he definitely wasn’t going because it was so close to my due date and he’d most likely miss her birth he promised over and over again of course so I trusted him fast forward to June he told me he had to go back to his country for a student visa to attend university here in the states I believed him up until yesterday he hadn’t spoken to me in almost two weeks while over where I thought he was and I started to become suspicious I did some digging and i found his secret Instagram account he had been posting pictures from GREECE not the Netherlands where he told me he was I followed his account didn’t say a word I just followed him he sent me a simple text right after he saw that I had followed him saying “I’m sorry I didn’t move on I just wanted to get away for a bit” then immediately blocked me after sending it I was so heartbroken and confused why would he say sorry then block me?? I spent the whole night crying and feeling so many different emotions I woke up to another text from him then after that text he blocked me yet again I can say it’s safe to assume he obviously does not want to be with me but I just don’t understand any of this he lied to me for months and acted like everything was perfectly fine filling my head with so many lies about loving me and wanting to spend his life with me I can’t wrap my head around this all he is acting as if I did something wrong to him by blocking me and sending me that nasty text just a few hours after he had said he was sorry I’ve known this man for 4 years I’m carrying our babygirl I love him to pieces I’m so beyond broken right now I don’t know what to do.
