Reverse ..
You tell your wife you bring a female friend in your house to sleep over for some days for whatever ( honest ) reasons . The female friend you brought is attracted to you , you LOVE her company and you do exactly as Elli did all these days but without anything more , just great company , endless talks , sharing fun times for people , life , anything . Again , she wants more but you say you have a wife and that you love her . But she still wants you .
We escape the obvious ( you would ask her politely to leave because you only wanted to host her as a friend , you deny each and every move towards you , your wife agreed first place to host her ) , should your wife go and file for divorce because you were just spending time with your friend ? Because in the end you WILL NOT HAVE BANGED the friend but she still believed you lie because of the all nighters .. what do you think of this ?
Between a couple , there’s a basic fundamental element needed to be alive and exist . It is called TRUST . If there’s no trust , what’s the point ? Sayn trusted Elli with blind eyes because he hadn’t been getting any indications that there’s something happening . This means he didn’t know his girlfriend so well . The relationship is already broken but most examples in life show that the “ weak “ ( in our situation Sayn ) forgive but not forget of course , they give one more chance because they LOVE the other so very much and they believe that this person will change .
I said it during the day , I think Sayn stays and gives one more chance to Elli. Elli becomes a complete “ nun “ and we as viewers will be watching Elli for her beauty and post here an one 30 pages topic in 2 months 😁
