Religion and relationships

Catie
Okay so this is gonna be a bit long but please read and give me some in put. Alright so me and my boyfriend met back in high school when I was 16 he 17 and we reconnected in college me 18 him 19 and have been dating for the past 2 years now. At the begginng of our relationship he told me it's going to be difficult and he didn't wanna put me through it because he knows wel have a hard time due to his family. I was in love with him though still very much am and I went for it. I am very supportive and understanding when it comes to them because I know it's just as hard as him as it is me to put up with it. They have yet to meet me because they simply do not want to. I occasionally talk to his sister in Facebook and she likes me and I've met his cousins who love me. But idk it's such a heavy weight on my heart, I want to marry this man and him me. He's given me a promise ring because he wants to one day make it an angagment ring but of course not until his family is on board. I'm just lost at times thinking about it. What if they never accept me? Our religions don't bother us we talk about it all the time how we'd raise our children and how we'd live neither of us pressure eachother and were crazy about eachother but I know I can never come before his family. I guess I'm just looking for advice or any personal stories that can relate?? I've met some of his parents friends and talk to them about it and they love me tell me I'm a beautiful and sweet girl and to just be supportive and give it time but how long do I wait??
