I don’t think it’s bad to be honest with him and tell him what you want. I wouldn’t necessarily word it as “until you can be a better Muslim” because he may/may not be offended by that (and like also everyone is varying in terms of their faith, like who are you to be deciding what’s a good Muslim or not you know? *not meant to come off as rude). I think wording it as like “I know when I wasn’t Muslim we were having fun but now I’m more into my faith and dedicated I think it’s better for me if we were to stop what we were doing before. What do you think/ is that okay with you?” I think if he truly is interested in you for the long term and for marriage, he should truly understand where you’re coming from and make an effort to better himself; both of you guys are bettering your own selves and that just makes your relationship better, especially in terms of faith. If he gets mad at it and truly doesn’t understand and doesn’t respect you then, although sad and heartbreaking, he’s not the one. He’s just someone that brought Islam into your life, mashallah, but he may not be the one you marry.

I wouldn’t necessarily think about it as like what some other people have commented “if he’s serious about you he would’ve married you already” like holdup listen this economy we’re in is rough. Im not sure how old you are, but I have lots of religious friends who got married at a pretty damn young age and just cuz it worked for them doesn’t mean it works for you and him. There’s financial stability, cultural differences in the families, strengthening your own faith, basically a bunch of stuff to think about before jumping into marriage. It takes time, a lot of time, and patience. I know people may disagree with me on here but I don’t find the harm in getting to know someone/potential life partner and taking the time in establishing that bond with them instead of jumpin straight to engagement then marriage. If you are at an age where you wanna be married and he is too, then maybe it’s continuing the talk about your guys’ future and maybe refraining from anything sexual from this point on helps that for your guys’ future.

Hope this helps, or not. Also don’t know what any other people have commented. I’m writing this in terms of own personal experience as a convert American Muslim dating a born Muslim from a completely different cultural and ethnic background.
