Prince Charming found…with one flaw

Hey guys!

I’ve been talking to a new guy for a while now. He is the first guy I’ve been serious about and really had feelings for since me and my ex broke up 2 and a half years ago. He’s amazing - funny, kind, gentle, smart, hard working, and amazing to both me and my dog. One problem though. He SMOKES. Like a pack a day. I have asthma and made it clear from day one that I would appreciate him not smoking around me, which he has been very respectful of. However, obviously his clothes and vehicle smell of smoke. I am a nursing student and smoking is a risk factor for pretty much everything, as I’m learning so that upsets me as well. He doesn’t know I have an issue with it, and it isn’t something that would be a deal breaker for me being with him, I would really like to see him at least try to quit though.

Any ideas?? How can I bring this up without making a big deal? How do explain and validate my concerns? Should I even say anything??
