Married not in love with my husband. met someone and fallen in love. should I leave husband?

Do you have kids? If so and they are not grown up yet, I would say you should think about them and how a divorce would affect them. You also need to think about whether it's only the fact that this person seems new and exciting or whether you truly do "love" them. Otherwise, yes you should. You should never be married to someone you don't love

“if you love two people at the same time, choose the second. Because if you really loved the first one, you wouldn't have fallen for the second.”
― Johnny Depp

if u have kids then u can't leave him bcs yr kids are impourtant if u have not it will The decision is up to u
