seems like she's making demands already?? first, she wants her sister in UK with her then she wants u to convert religion?? who is wearing the trousers here?

As the old saying goes, love conquers all. People who are in different religions can definitely make a relationship work but of course it's up to u..u might like the idea of converting to her religion then go for it who knows it might be something interesting to u and open your eyes to some new experiences but also be aware that it's a lengthy process. Make sure to thoroughly discuss it with her first because it's some major decisions that u're going to make..not easy..it is definitely very important to talk about ur religious beliefs before you get ur emotions all wrapped up into it ...you need to know where the two of you stand alrighty?!
