im so paranoid

A while back my boyfriend was talking to a ton of girls on kik, ever since then im just so paranoid about him cheating. He just got a new job and said he has a 'cute' coworker and i think he could tell that made me nervous so he said she had a boyfriend. Well today he pulled up his emoji keyboard and the most recent one was 😘. Hes never sent me that and im worried hes talking to her at work. Idk i want to say something but i know how psycho that is to say. Im almost 12 weeks pregnant with his kid btw so i dont just want to up and leave.
