Mahiya,
You're 16 **right? **If so, I'm sure as a student you've got studying and other things to do. I think that when you attempted to talk to ur cousin last time, you weren't able to fully explain yourself and he made the assumption that you were fine with his wife bugging u all the time. But this time, be a bit more clear. I understand that you don't want to come across as being rude to your cousin as that can cause problems in the family.
You can try talking to the girl yourself. You can say that,
"Baji, I'm so sorry but I won't be able to talk as often or as regularly with you because I'm just swamped with so much work from school and what have you. And I hope you don't mind, but I need some space/break** to get things done otherwise I'd be talking ALL day and will get NOTHING accopmplished. I hope you understand. This will give you a break from me.....and I don't want your husband and the rest of his family to think I'm hogging a sweet person like you all to myself, LOL."**
**
^This will be a nicer way to give her a hint that u need space**:)
Or if you think it's better to talk to your cousin about it then use the same above explanation. Say:
"Bhai, I really enjoy talking to your wife, but I won't be able to talk as regularly or as often because I'm swamped with so much work and what have you from school. So, I hope she doesn't mind but I need some space so that I can concentrate on my work otherwise I'd be talking all day and won't get anything accomplished. Your wife is really sweet and it has been a pleasure to get 2 know her. I hope that you and your other family members don't think i'm hogging her to myself, because i'm sure they would also appreciate the pleasure of her company as I have."
^ Hopefully this won't offend your cousin because you're giving him a valid understandable reason for not being able to talk to his wife ALL the time.......and that reason is being a student and being busy! And you're saying nice things about her, so he shouldn't take offense. At the same time, you're hinting to him that she should also bond with **other **family members as well:)
You can try asking your cousin's wife if she's made other friends in the family. And as gulab jamun suggested, u can help her to meet/connect/bond/get-to-know other members of the family....although her husband (ur cousin) should b the one to help facilitate the family bonding.
And as GJ suggested, please don't feel compelled to respond to each and everyone of her emails. If you do that.....then she'll EXPECT you to respond all the time because you're allowing her to get used to it. I don't respond to every single email from my cousins or closest friends. So, don't worry about that.
The other suggestion I have is that you can talk to your mom **about it and see what she has to say about it. Your mom would have a better understanding of the family and can suggest some **tactful ways to go about the situation. Best wishes, Mahiya:)
In order to AVOID mind games and guessing games....its BEST to talk directly to SOMEONE....either your cousin......his wife......or your parent.
