A friendship is a good foundation for a romantic relationship. Often a friendship develops into more than "just friends" and a deeper romantic relationship begins. The difficulty can lie in recognising the signs, namely when you have romantic feelings for each other that are beyond friendship. 

The signs are different in every friendship. Only attentive observation of the dynamics within the friendship can provide clues as to whether it will develop into something more.

Realise how you feel about your boyfriend. How do you feel when you are together? Do you feel the same way when you are with other friends, or is there a physical attraction that goes beyond a platonic friendship?

An almost certain sign that your feelings have become more romantic is when you become jealous. Or you constantly think about your boyfriend or girlfriend when you're not together and you can't wait for your next date. In any case, before you talk to your friend about it, you first need to be clear about your own feelings.

Observe what others around you think of you. You often overlook the signs because you are affected yourself and many things become clearer through the eyes of those around you. Friends around you usually see the romantic development earlier than the couple themselves. To find out more about what others think of the two of you, you can observe their comments and reactions when they see you.

If you know that your feelings go beyond those of a platonic friendship, you should talk openly and honestly with your boyfriend or girlfriend about it. The feeling is not always mutual, but sexual attraction often develops between the two of you. A strong romantic attraction often arises when both have strong feelings for each other and the spark is ignited.

If you and your boyfriend both feel similarly, you should go on a romantic date and test the relationship. But let the relationship develop slowly and naturally: If there really are genuine feelings of love between you, the relationship will grow all by itself.

However, if your friend doesn't feel the same way as you do, you have to respect that. To maintain your good friendship, you need to back off until you have your feelings under control. If you try to "get" your friend, you will lose him.
