I would wait, remember, you must be absolutely sure that you two will never leave each other, EVER. Since divorce is unbiblical.
But, eventhough I have no experiance here, I do understand how it must be. after being in love for how many years? It must be kinda hard to harness oneself.
But please be faithful and wait, it's no longer than 1 or 2 years, right? If you can make it this far, you can make it further.
Oh what joy your weddingday will be then!
But yeah, I suggest telling your BF about what your father says. And I'm getting kinda convicted here, lol. thanks.
Well anyways, lifting you up sis!
