Marriage is a big thing in the muslim culture, in many countries you are not allowed to see each other let alone live together without marriage. This wouldn't be just his perspective, but a perspective of his family and all close relatives and their friends living in your country or back home. This is not going to be easy to resolve the pressure will be there and in the end something will have to give, you will have to succumb either to the pressure from your or his family, so choose wisely.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
