I think you should be getting the point by now on what people here think.

But to answer your question: No, your worries are valid and it's not just you.
Pro/Con lists are good and all to help make important decisions, but when the con list has those sorts of issues...tread with caution. I've known men like that. They have a whole act that they portrait in public that draws people to them and puffs up their own self image as being a great guy. But behind closed doors they show who they really are, completely self-absorbed.
You're pro list is full of stuff relating to others: work, family, son, strangers...
You're con list is full of stuff that concerns YOU: temper, sneaky, lying, tendency to cheat, money pressure...
You don't marry someone for how they are with others or in public, your marry them for how they are with you in private. You have at least been with him for 5 years, that's a long time to date and so you've probably had a chance to see all sides of him and know what you are getting into. As Deejo said, you aren't going to change him. You have to think hard about all those negatives, picture dealing with them the rest of your life, and then decide if you are up to that or not. Some people are. Some people are just too worried about being alone and finding someone else, that they can live with the negatives. The question is, are
you ok living your life with those sorts of issues?
