Is it awful of me to doubt being with someone for this?

Nope – each one of them sounds like a deal breaker to me; with all of them, I can’t imagine why you’d stay with him!

No, the first two he could work on, but honey, being good in bed is a deal breaker.

Generally those aren’t deal-breakers in and of themselves or even in combination, because people overlook those bad qualities (and they would be considered bad qualities by nearly any non-smoker) all the time “for the sake of true love”. But if you’re already on the fence for other reasons, then they certainly aren’t reasons to stay, either.

It sounds like you are busy finding faults. If your relationship is at that point, dump him. He isn’t right for you.

How does he afford cigarettes if he doesn’t make money?

Why are you using the word “doubt”?

The only thing I slightly judge you for is the money and snoring, but everyone gets to choose whom they are interested in being involved with or not. You don’t even need reasons.

No. Get outta there. Life is too short. If you have doubts end it and move on. Do not get married to him RUN.
