Sims 4:dying of embarrassment

now I've had the sims for 2 days now and i've managed to make two lots already. but the thing is i managed to get two dates and proposels successful, did a third date everything was fine but the boyfriend didnt accept the proposel and left my character Mortified, im ok with that. but when the character got home she went for a shower then i sent her up to her bed to hide from people. then all of a sudden she dies of embarrassment which i found annoying, i pleaded to death with the mother (i'm also an idiot as i used the mother on the grandparent so it didnt work) and the daughter dies. luckily i managed to not save my progress (and i didnt care as i only played with that character for the date) but if your going to do a dating thing dont make the character go hide from people if had been Mortified twice.
