Advice!

So I (23F) have been in a relationship with another Muslim (27M) for about 9 months and it’s been relatively good. I would say I used to try to pray 5 times a day prior to meeting him but he doesn’t pray, fast, or have any faith it seems. It has made me lazy and neglecting my prayers when I never intentionally wanted to do but now the guilt of it has come up. There have been a lot of stressing and saddening things happening in my person life and I know the only way that can really help me is praying and staying a good devoted Muslim. So I’ve gone back to praying and it’s making me feel better but I also want to stop doing certain non-halal things with my boyfriend but I am scared on how he is going to take it. Idk if I should have a conversation with him about how I want him to pray and start fasting but I am just nervous on it all.
