Am i in the wrong to end it with a message?

So I went on a couple dates with this guy and on his birthday weekend this last weekend we spent 3 days with each other. Within those days, he brought up his feelings and wanted to talk about where we were taking things and how he wants to keep taking me on dates and that us being around each other doesnt always have to end in sex. We had a really great 3 day weekend, I stayed at his house and we just got really intimate with our emotions and physically. I hadnt brought up anything about becoming anything because i was hesitant to. I found out he had gotten out of a relationship a couple months ago, and the reason it ended was because he cheated on her. The second day we started talking, his ex told me he was texting her trying to reconnect. Which is fine being that we had barely started talking. But he had asked me if he could see me again Friday for a date if he doesnt work OT, he works graveyard shifts. Well between leaving his house Monday and to today, it seems like things have shifted. Monday night he thanked me for making him feel special and saying he was hoping he didnt get ot so he could see me. Yesterday he told me he slept all day before his shift, and today I text him good morning bc I fell asleep last night, we were texting and he told he just got home and I told him I was heading to work and he hasn't said anything.

Im sure he's ghosting me atp, but after all this effort he made and big talk he did (that he really didnt have to do because I didnt ask about it) he switches up. He was just talking about buying new pillows for me and saying he was missing the better half next to him this morning and what not. I expected this so the shock is wearing down because I know I should have expected anything else, but am I overreacting or should I send him a message and end it? he doesnt know that I know about his relationship past, and I want to tell him about being aware of it and that he needs to work on healing. please be nice to me, I know this sounds dumb but the amount of bonding we did was intense and he was the one to bring up a future and whatnot, now my feelings are just hurt but I feel like no one really told him anything about himself so I feel like I should. Any thoughts or advice? This message would be mostly for me, not for him.
