You meet a girl/boy.
They are adamantly religious and you're adamantly not. But as friends you both have tolerance and easily stay in touch. After a time they fall for you and says they'd give up their religion to be with you, un-provoked desperation it seems but you don't know for sure.
Do you
A: say yes, let them and become a secular couple
B: say no, you refuse to let them change their religion/beliefs for such a reason.
E: friend zone them.
C: say no and try to work it out as a couple while each retaining respective beliefs or lack thereof
D: you dont do any of these
B. No. A person's religion is deeply personal, and they should never give it up for a whim. What would likely happen is that they'd end up resenting their partner for "making" them lose their religion.
Tell them instead that if they'd like to know why you are adamantly not religious, you'll go out to coffee and outline your thoughts on it for them. Respectfully. Then they can go home and compare your thought with their own notes and see if they more fully agree with themselves, or more fully agree with you, or need more information or time on both. If they want to de-convert based on logic/thought process, with NO promise or guarantee of a relationship, then you can go forward.
If they'd like to keep their religion, the two of you could still be together. Just set ground rules-- you respect their religion and/or religious times (in other words, don't make plans for Sunday mornings and such), and they never try to convert you. If either of you break the ground rules, re-evaluate or call it quits until one of you budges
based on logic/thought process only!
When my husband I got married, we were both religious because our families were. My husband was less religious than I was, however. He had in fact been asking his boss to intentionally schedule him to work Sunday mornings just so he could avoid church without his mother raising a fuss. I knew about this, and I didn't really care.
He went full atheist a couple years before I did, but he never pressured me about it. In fact, since we never went to church after our parents weren't making us, we never talked about it, period, until I finally told him I didn't think I could believe anymore. It was only then that I realized that he, also, was an atheist.
Moral of the story is, two people can disagree on some things and still love each other. They just have to agree to respect each other, whether they respect the belief or not.
