Dear Brian Cyr:
When you feel an interest in a woman there is the possibility of a wonderful love story to take place but also the possibility of a heartache. Or both. So better approach the woman (and these possibilities) with some caution. Gather information from the woman so to make the best choices you can make so to increase your chances for a love story and decrease your chances of a heartache.
One question to ask her is if she is involved in a relationship with another man. If she says she is otherwise involved, better make the choice to not pursue her further and to look for a woman who is not otherwise involved. With a woman who is not in a relationship, your chances of a love story are greatly increased.
There are other questions, more information to gather before investing (emotionally and otherwise) in a particular woman.
