you have already been through such a situation and he promised you that he wont do it again and you already had a “talk” with him then if i were you i would definitely involve my parents.
I didnt involve my parents because it was the first time and he gave me the password with in the beginning of our marriage with out me asking him… being his wife and sometimes out of bordem i would check his mails… not that i was looking for some clues of him cheating on me… jst when i miss him i would go through his mails that he sent me and the mails i sent him in his account and jst read 'em over…
and thats how i found out couple of mails in his junk mail and that made me curious and i tried checking his other accounts which happen to have the same password (he didnt tell me the password for that account) well i confronted him…
i couldnt involve my parents due to some problems in the family beside after marriage i believe the less your family get involve in the issues the better… BUT you are only engaged and you are still in your parents’ house and you still have a chance.
Talk to your elder sis if you have any discuss it with her or if you have any elder brother talk to him and explain to him the whole situation and tell him abt the past time you and he had a “talk”… and then listen to what he or she has to say… then talk to your parents…
You can confront him but dont do the mistake i did… ask him first if he has time and what he is doing and where is he at… cuz u dont wana give him time and come up of an excuze
Do consider yourself very lucky that you found out before you got married to him…
and dont worry … there are many lovely people who are definitely gona give you some good advices (ofcourse there are some who have no such exp and they would give you stupid advices and i am sure you are smart enough and old enough to judge that)… i have always found RedVelvet, PS (bonbonniere) and Somehowcollide’s comments/suggestions very helpful and they always talked senseable… i am sure there are many more people who give gud suggestion maybe i just never had enough time two get to know them…
