Thanks for all your replies. I'm going to think really seriously about this. The thing is it's really sensitive, this religion thing, he's Muslim and I'm a Catholic, and some of the youth in my Catholic community have converted due to relationships they had, similar to mine, because of the country that we live in. I've always been grateful to my community because I've experienced a lot of love, and I don't want to betray them, especially the priests in my vicariate who thinks I matter and love me and pray for me.
In my head, logically, I just straightaway assume I don't see a future with this guy, but...realistically speaking, it's not that simple. Feelings will always be there and it's not going to be easy to separate once we were together during uni. But I'm just so afraid of the law and what they will do to us if I get married to him and refuse to convert. But at the same time, i feel it's unfair that religion is a barrier in my relationship.
I'll give it some more thought and come up with a decision, but I would appreciate any feedback at all in the meantime. Thank you all for your thoughts and advice!
