It’s really sweet in the start, and, you would kinda feel like, it will last forever. At first, you would define it as being in a relationship is happiness but as days, weeks or months passed by, you will learn what truly love is. In a relationship, fight is inevitable. Even how much both of you keep away of that, you will really feel those ups and down, circumstances, worse or dark days etc. For that’s life. You have to deal with it but, together with your partner. For this is life of being in a relationship. You have to give for you to take and vice versa.
