It is better to have others be pleasantly surprised than it is to have them be disappointed because you have stirred up their highest expectations. If you are interested in someone, be ready to supply a recent photograph. It is reasonable for others to want to know as much about you as possible before they invest in meeting you. It is okay to give only your work phone number to someone until you know the person better and feel safer. Be open to all kinds of relationships.
Romance is only one possibility.
Lots of friendships are created through online connections. Once you meet, you still have the same job that you have always had when dating. You must spend time with someone, develop your connection, communicate on deeper levels, and allow time and your heart to tell you if you have found your Soul Partner. Take care of yourself - it is true that there is some risk involved in this way of meeting people, as there is in other ways of meeting. If you practice honest, openhearted communication, and you trust your intuition, you may find that this way of meeting and dating can be immensely rewarding.
