In regards to a platonic friendship, being able to talk about issues to that friend can give you a look as to how the opposite sex thinks and why they act a certain way. Often in a friendship of a man and a woman, they will go to the other for dating or relationship advice. Women are usually very confused about why men act the way they do; their male friend can help them understand. Men are often very confused about why women act the way that they do; their female friend can help. Same sex friends, most often, while being able to lend an ear and a shoulder to cry on, are just as confused as you may be.
When a man and a woman are friends for a while, they may feel very close to each other; so close that one or both of them wishes to bring the level of friendship up to one in which they become the romantic friend of the other. This can sometimes work however there are elements to consider.
If only one person has the notion to change things and be the romantic friend of the other, most commonly the other person will protest. Their reason will be that if the romance does not work out, they feel they will lose the friendship. Good friends are hard to find; and the thought of losing that friendship will not seem worth the chance at having romance. Other times, one person may be very close as a friend, but will not the attraction and feelings that are needed to be a romantic friend of the other.
If wanting to expand the friendship, an important factor, is to test the other person to see how they will respond if you want them to be a romantic friend of yours. This can be done in a non-intrusive way and slowly. You do not want to scare them off. If you are a man, you can bring flowers to your female friend. You do not need to make a big deal about it, just casually hand her a bouquet of beautiful flowers and tell her that you felt she would like them. See how she reacts. Does she quickly say, “Thanks”, puts them in a vase and immediately begins talking about the date she had the night before? Alternatively, if she takes the flowers, smells them, looks at them with a smile and takes great care to put them carefully in a vase; she is most likely showing that the flowers have great meaning to her.
If you want to see if your friend can become a romantic friend of yours, take them out to dinner, but not a causal one. Announce that a great night is in order. Make reservations at a classy restaurant. Ask your friend to dress up; you are taking them out for a great evening. Be sure to dress a step up from what is normally expected. If you are a man, add some extra cologne and an a classy tie. If you are a woman, wear a sexy dress and new perfume. Judge the way your friend acts. If they compliment you, smile at you more than usual, you are off to a good start. A person who wishes to accept being a romantic friend of yours will be receptive to flirting and you should flirt in a way that shows respect and caring.
If you see that your friend appears to be open to the possibility of being a romantic friend of yours, it is time to talk. When you are both feeling comfortable, you should talk about your feelings. Do not jump to saying you love them; simply state that you have feelings for them and that life is short; it is difficult to find a great partner and to not look at the possibilities to be together would be a shame. Talk about this in a way so that they person does not feel any pressure. If they are concerned that being a romantic friend of yours may ruin the friendship bond, reassure them that this will just be an experiment. If it does not work, no one can stop the friendship that you share.
