I'm interested in a Pakistani girl and time is running out

it will never work, just being honest.

Wasting your time. Not worth it. Plenty of beautiful Sikh girls.

I'm assuming you are a Muslim.
And yes I agree, there are beautiful Sikh girls out there. But this is different. Remember beauty is subjective. I just feel I've never met a girl more beautiful than she. So it is most definitely worth it.

Yes. My comment is based on my own experience as a young man like you, who was very interested in a Hindu girl (it was mutual). Fortunately for both of us it didn't work out in the end, just short of marriage, for the best I would say, even though we were not religious whatsoever, so that wasn't the issue. You will like me grow older, wiser, and realize you're better off not involving yourself in these type of mixed-faith relationship. Too many unknowns. You can change, she can change and become religious. Best sticking to something that doesn't involve you having to change and compromise, and the same for her in order to get married. And that doesn't have the risk of someone becoming a different person in the future, than the one you married.

You're young, so it's quite normal to feel that you haven't met someone more beautiful. As you grow older, and meet more people, experience more, the less beautiful she will appear and you will end up laughing at yourself when you look back and wonder why you were desperate to get her approval.

It is not worth it. I hope you don't find out the hard way.

Wait ... Encourage her to practice her religion??

Either you intend to convert to Islam, or not aware that she cannot marry a non-Muslim. Or she doesn't believe it's forbidden to marry a non-Muslim. I doubt you intend to convert, and it's probably already came to your attention that she can only marry a Muslim, and if shes's quite religious as you say, she would know it's not permissable to marry a non-Muslim.

So which is it?

I don't intend to convert to anything at the moment. I am open to considering it if I believe that another religion is right for me. But I must do more research in order to do that.
I'm sure she knows it's not permissible to marry a non-Muslim, but I still intend to go further with it.

Actually she was in my dream last night and I asked her. In the dream, she knew I was interested in her this whole time and needed more time to make a decision. I think this is a sign.

Which is what I don't get. You can't claim you will encourage someone to practice their religion, while planning to get them to do something not permissible. It doesn't make any sense. So basically you want her to break a rule for you by being with you, then you will be supportive regarding the other rules (as long as they don't make a difference to your lifestyle). And when you come across those that do, again get her to do something prohibited. You're supportive as long as it doesn't effect you. The religion has many rules, so in the end, you would be doing the opposite of encouraging her to practice it. It's not like other religions, people choosing what suits them and ignoring which does not. It's practiced as a whole. You said she's quite religious, so I don't think she and/or family would approve.

Yes she wears the hijab. And that's got nothing to do with why I haven't asked yet. I'm just a very nervous guy. I've only ever asked one girl out and that was when I was 12 so it doesn't really count.

I don't see why her family would not approve. Even though it is prohibited, I really can't see why.
I really can't see any problems between a Muslim and a Sikh getting married. Our religions are very similar.

So to have to mention this but as you are a Sikh have you even thought what your parents will think?

I know people will say 'as long as they like each other' and this is quite a different matter, especially considering the tension between muslims and Sikhs.

I don't see why her family would not approve. Even though it is prohibited, I really can't see why.
I really can't see any problems between a Muslim and a Sikh getting married. Our religions are very similar.

Why not? I can't think of any reason. It's quite a simple procedure if she says yes.

Actually my parents have told me that I can marry anyone from any religious background and from any ethnicity.And the tension is all a lie. There is no tension. I have so many Muslim friends. More than Sikh friends. Doesn't make a difference.
