do yall think im over exaggerating

Me and fiancé have been really happy planning our wedding, he has a carrer, becoming financially stable etc. in the past i did have to tell him to get his shit together or else i was leaving because he kept lieing about applying to school etc. so hes almost done with barber school he just needs to pass the test, he failed once i said its ok try again he did and told me he passed. I called my mom, made a huge post on fb and we celebrated. But i find out he lied i question him about it and he admits he lied i have no idea why and i just hate that he lied about something so petty and feel i cant trust  him.
