Due to horrible allergies smoking is an automatic elimination. Active criminals need not apply either.
I have to say being a drug therapist, any illegal drug use is a deal breaker... and someone who is not in a stable position in life.. someone who is actively abusing alcohol, not taking care of themselves...a man who has not annulled their marriage... I know it sounds picky, yet I have tried to save guys in the past... and I need a man who is stable in life & ready to commit to a wonderful woman like myself :)
I got out of the business of trying to change people a long time ago, you can't jump on board the ship and then complain about the destination. If they live a lifestyle which is at variance with the faith or morals of the Church, chances are you're probably not going to change them (at least not completely), and if they are reformed, then once again, the odds are they would be in accord with the faith questions, rather than continuing to answer to the negative.
One of my immediate deal breakers is a negative answer on the faith questions on the use of contraception, premarital sex, and a desire for a very small family (1-2 children). Generally speaking, this can be indicator that this individual lives (or seeks to live) a self-centered lifestyle which sees living a lavish or stylish standard of living (or travel/spending habits) as its catalyst, where 3 or more children could present an economic barrier to that; the same may be said for sexual habits wherein it may have been a tool of recreation for them previously and could continues to serve as a test drive for new partners. This sort of person may be more likely serve you with good bye papers when they no longer "feel happy", or when the going gets rough financially.
