No, they shouldn't date because they'll end up having different ways of dealing with stress and when one goes through a major stress in their life and has a few meltdowns (a few minor, and one major) then the other one will be scared off and the relationship will never be the same. Then they will never meet someone else they are happy with and will always miss the other person's kiss and will be depressed.
