Thank you all again for the comment, critical or not, it helps.
We have been seeing each other for just over a year. I am all for compromise, she's already banned me from eating pork lol, she won't kiss me if I've eaten it, plus it really annoys her when I eat it so I've just stopped eating it all together. I have accepted that some things about her are different to my way of life. I do not smoke or drink alcohol or do drugs anyway, I'm sensible.
I understand that the breakup is terrible which is why I wanted to try and get things back on track. The problem is she is totally fine with me not being muslim, it's not like she is pressuring me and I'm fighting with her over it. We've spoken about religion like three or four times just during random conversations. The only thing we argue about pretty much is what restaurant to eat at (halal only, that's ok by me) and what movie to go watch lol. She's super chill. My family fully accept her, but I do fully understand how poorly frowned upon bf/gf relationships are and marriage to non muslims.
Maybe if I start learning about islam she might start practising more and who knows, I might even believe it. Then we could transition to an islamic marriage of some sorts. It's a long shot but at least I can say I tried it.
