Overanalyzing 😒😒😒

My boyfriend just texting me saying we need to talk, and so I said ok let’s talk then. He didn’t reply for like 20 mins, then said “sorry I don’t know why I said that”. Today he also disappeared for like 2 hours and when I asked where he went he said “going to the job interview like I told you”. He didn’t tell me anything about a job interview lol. Is he talking to someone else or am I going crazy 😭 he cheated before & im having a really hard time trusting him
