Hi girl,
Firstly this isn't a problem. It's a phase which many youngsters go through.
Let us start by looking at positives.
- Your parents have agreed.
- His parents have agreed.
- Your relationship is rock solid.
Now let us focus on small hurdles.
- Firstly, discuss with your partner and check whether he wants to get married now or wait till his elder brother gets married.
- Second, if your partner is ok with marriage now, then it will be great if ur partner can convince his parents for your marriage.
- If your partner is not ok with marriage now and if he wants to wait for his brother then you both should consider the situation and come to a mutual agreement - maybe give a certain time period like 6 months to 1 year. If his elder brother gets married in this duration then good. Else you both should proceed with ur marriage.
- Meanwhile you should try and make your parents understand that u are a matured independent individual and you should convey ur decision to them.
