cheaters

I've been here so many times to read about people's posts. And it makes me sad to think they're so many people out there whose significant others cheat on them while pregnant, or not for that matter, no one deserves that.... I have been cheated on before many years ago (while pregnant with my first), and lately( the more I read stories about finding out about their love ones cheating) I find myself worrying more and more about this. All I want to do is check his phone to make sure, but I would feel entirely too crazy to look out of nowhere. Things have been rough financially since I got pregnant so there has been a lot of stress on us. Is there any others out there that get like this. Or is this just crazy pregnancy hormones plus stress messing with my head. 😓 idk what I should do. Any advice is greatly appreciated.
