Interfaith and Intercultute Relationships

I am a white british woman currently speaking to a british pakistani. I know that inter culture relationships are frowned upon often and he’s been quite open about the fact that his parents are very protective over him and he hasn’t been allowed to speak to girls in the past. We’ve been speaking for about two months now and I am starting to think in more longer term. If any of you are from a similar background as him could you offer any advice as to a way forward? Would I ever be accepted into his culture as a white british woman? We are very compatible in so many ways and I would hate for a culture barrier to be the reason we couldn’t move forward somehow. I was born into a Christian family and I have read that it is permissible for a Muslim man to marry a Christian woman but I don’t know how realistic this is in real terms. If anyone could offer any advice I would be really grateful!
