Am i tripping... ? Or does this sound weird to anyone else ?

Okay so idk if im tripping or whhhatt 🙄 i dont wan jump to conclusions & shittt butttt first , my boyfriend was texting his ‘manager’ (he said thats who she was) like it seemed flirty but idk im also 8 weeks pregnant & she mentioned our baby also so i asked him how did she know we had a baby on the way... he says “cus shes my manager” fine cool i let it go... but the only thing that didnt sit right with me was the fact that he NEVER EVER EVVVER mention a female manager 😂 its always “he said this” or “HE said that” like he literally never said anything about a “her” which really confused.. idk or im tripping🤷🏽‍♀️🤷🏽‍♀️ BUT also today i just seen on his phone that he changed his messages that pop up on his screen and when they pop up its says “notification” so i cant see what it says and from SOME apps i cant see who sent the message at all! He has never done that or anything so i was confused .. i asked him about that he says bc he doesny want anyone from WORK seeing his messages... im like ....

First of app dont they know you have a whole baby on the way😂? Second of all you are grown! & 3rd of all..... why tf isnt ur phone in ur pocket?! 😂😂😂😂 like I literally text him wen hes at work and ik its never or the charger or anything! 😂 soooo now im wondering 😩 like im trying not to stress bc i am pregnant lol & also a frw months ago i found out he was texiny his 2 exes for MONTHS! Behind my back!!! Since like February up until like August 😒 he had a whole fake facebook texting them! I didnt wanna read all of it bc it was so much and i was soooo broke 🥺 i know i seen a few “i love yous” and shit...... but Supposedly it wasn’t like that..... whatever. But i ended up letting that go🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️ he says it wont happen again but something isnt sitting right with him right now.. im getting that ‘feeling’ again... i told him that but he said he doesnt know why i feel that why cus he isn’t doing nothing. But he said that beforw n turns out he was 😫😫😫. But yea back to what i was saying i just find it weird he made his messages like that. Like u dont live at work😂 why u gotta change shit from them? Like tbh who are you really trying to hide stuff from? Me or someone else ?
