Re: What should I do? 
And even IF he feels that way…so what? The other girl’s family is their relative so they’re not going away. Even IF…and this is a major IF…the guy fights for OP and they get married…at the end, OP will be the reason behind causing MAJOR family drama on their side. There will be certain members in that family who will take the other’s girl’s side and will be resentful towards OP b/c they will view her as the “outsider” who caused tension in the family. This will lead to drama/arguments/tension etc…and there is a good chance the guy will put in situations where he’ll feel stuck between his blood family and OP. I could understand OP fighting to save this if they had been dating each other for years and actually were at a point where they (guy and her) had an actual relationship…not just exchanging formal texts for a short period of time due to an arranged situation.
There is already hints of drama if OP pursues this and gets in that family. Just read the other threads here where wives are dealing with unhappy marriages. In almost all the cases, there were warning signs before…some of the women knew that they weren’t the #1 choice for the in-laws. Yet they chose to marry in that family anyway and now are dealing with regular drama/tension/arguments as a result.
