I believe that love is when you love a person soul. And sex is physical attraction, because sex can be practiced without love. But it is possible to note the fact, and many probably would agree that it is much better to have sex when experiencing feelings of love for this man. The sex becomes more imbued wonderful emotions. In his youth, many just have sex without thinking about love, and at an older age and we want love and sex. This is just my personal opinion about this issue. But clearly sex is fine in romantic feelings.
well, depending on what situation caused the separation. If you decided to break up mutually, then there is no need to worry. If the guy threw a girl, most likely no need to try to get him back, you need to have a sense of pride, and generally if a guy wants it he'll bring his girl by any means. But in General if people break up, then it wasn't love because when you love, you will never go away man. And you should not suffer because someone who left you. No need to lock yourself in the bathroom and cry clinging to the pillow. Need to overcome this feeling and Vice versa to go for a walk with his friends, most importantly do not need to withdraw. We have to look forward, not to worry and keep believing that you will meet your true eternal love.
