a) You progressed to contact them over the phone, but the problem is you can't ever contact them! 

b) You have to page them for them to call you back. Only they will call you but you cannot.

c) They use a separate line. If so, try calling their main line at random times.

d) You can only call during certain periods of time. Again, if this applies to you, try calling at different time periods to see who answers the phone.

RED FLAG#3: Asks for money
Since you are dating only online, your relationship is not that deep yet that your date should ask for financial help. Asking for funds may destroy the relationship which could become a long lasting relationship in future. If you or your date asks for money, it may show that the person's financial condition is not very sound which may push you away from your partner. Avoid getting into financial trouble by following a simple rule; "don't lend or borrow money".

RED FLAG#4: The efforts to continue the relationship
Are you the only one making an effort in altering your lifestyle to have this dating relationship ongoing? Do you notice no efforts on other's part? This is a telltale sign of things to come if you develop an off-line romance. You should be aware of the fact that no relationship exists for long with solely one person's efforts. If you find this happening to you, talk about it to your partner and ask them to meet you half way in your efforts.

RED FLAG#5: Feeling of Insecurity
Is your potential partner is overly insecure about your off-line or online activities? Just as in any relationship, a person who is overly insecure about something can end up being an emotionally draining experience. Take a step back, and really look at whether this is something you're willing to put up with if the relationship happened to last two to three years. If not, move on and find someone more independent.

RED FLAG#6: Eager to get married
If you think that your potential partner wants to get married too bad, think about it seriously. His/Her eagerness to marry may be a sign of loneliness, rejection or feelings of resentment toward others. Such individuals sometimes marry to get out of their home or to avoid loneliness. However, they will often carry their past baggage with them into a marriage. It is suggested that couples take their time and not rush into marriage. Date a while and really get to know each other.

RED FLAG#7: Pressure for Sex
One of the biggest warning signs while dating is when someone is constantly pressuring the person they are dating to have sex. If your date pushes you for sexual favors, this is one of the biggest red flags. If you are uncomfortable with a person's advances, communicate that with him/her. You need to know each other more before stepping into such relationship. Their response will tell you how much they care about you. If they continue pressuring you, they are just disregarding your beliefs and values.

RED FLAG#8: Reality VS. Fantasy
There are many different viewpoints towards a dating relationship founded through the Internet. To save future hurt and embarrassment, make sure you know your potential partner's philosophies. Do they view an Internet dating as a real relationship, or is it a way to live out a fantasy life? If it's the later, be careful to avoid being their latest cyber fling.
