Unequally yoked & infidelity

Today, attended another event and there was some talk about why a Christian must marry a Christian. Surprisingly, not all Christians seem to agree...or rather they don't agree that you can't date a non-Christian, but the person can eventually be converted (it seems that mostly guys think this way, but an occasional female did say the same). Also, a lady friend of mine commented that it seems that it is "easier" for guys to get gals to convert rather than the other way. 1 person even said he had "no preference". It seems to be like some people think that "well, if the other party is a Christian it will be better, but we can settle for a non-Christian & they will eventually come around".
Huh?! Forgive me, I'm really sometimes very surprised/puzzled when fellow Christians think this way & I myself never considered such an alternative once I became a believer. Maybe it is the way of the world that changes people's perspective on such a matter as the relationship dynamics in society change.

Anyway, that's beside the point. I believed I mentioned earlier that if that's the case, you're more motivated for self-interest and there might be repercussions in future.

Ok, back to the chat. During the conversation, I seemed to have a sudden revelation or rather a light bulb went on in me to ponder if being unequally-yoked is actually like infidelity towards GOD. I am someone who cannot stand infidelity (as do many others). And seeking someone not of the same faith is like side-stepping the path which leads to GOD and succumbing to temptation outside the body of Christ. It's hard for me to explain why I suddenly had this in mind or felt this way, but it's like you're committing "adultery".

For me, I strongly believe in finding a Christian to be my bf and husband. Hence, I hope/expect the other party to share this same value as me, that he will only look for Christians to be his future partner. Although I don't wish to be judgmental, but it might reflect on how he looks at his faith. For me, leaving your options "more open" for people of other faiths is like opening a door to step into darkness or a host of temptations & danger. Why risk it?
It's perfectly fine to be friends with people of other faiths, but boundaries have to be put in place if there is a risk of going further incautiously. It's like walking on thin ice and as the ice melts (like the other person melts you :P), you can drop in anytime in places that are more vulnerable than others to be swallowed underwater. (Maybe that's why ladies are more prone to "melt away"?)
Ok, it sounds bleak but i'm pretty serious about it.

It's not about settling for something that you can have right now (even when you know it's against His will), but GOD honours those who are patient and willing to wait.

Do I sound very 专制？ I believe there are those who share this belief with me.
