I still remember that day vividly, when Ryan finally asked me out. I was so happy. I guess I had a crush on him for like forever. We never used to talk really, but met due to some common friends. That was the first time I met him.

And then we started hanging out, sometimes with friends and sometimes by ourselves. I really loved spending time with him. He was free to talk to, always open and frank, funny, sweet, caring and I just fell for him.

And then the day came when he asked me out on a date. And I didn't even hide my happiness when I finally said yes. So we started going on to more dates and got into a relationship. I was so happy to be his girlfriend and he was the perfect boyfriend I could ever wish for.

And on maybe Tuesday, when we went on yet another date, he finally said those three words, that I was dying to hear for the last 2 months.

"I love you Elsa." He said looking straight in my eyes.

"I love you too Ryan." I said as he leaned on to kiss me and I kissed him back instantly. I loved the way his lips moved again mine. And then he put his hands on my waist, to pull me closer as he depended the kiss. It was the best night of my life.

After that night, things got really nice. We started hanging out together even more. It was like everything was perfect. Just the way it should be.

"Promise me this is forever." I said.

"I promise, Forever and Always." He said as he kissed me passionately.

Everything went out perfectly for a year. And it was our first anniversary already. We decided that we should go on a little trip to celebrate our anniversary.

It went perfectly fine but something changed. I don't know what happened, but when we returned Ryan changed completely.

He started getting distant. He started avoiding me. He even ignored all my  calls and texts. And when I went to his home he was almost never there.

It just killed me everytime he did that. I have no idea what I did to make him act like this. Or was it really me, for this behaviour.

Whenever he was with me, he would try to avoid contact as much as possible. And when I kissed him, it didn't made me feel butterflies in my stomach like it did before.

I used to keep waiting for his calls or at least his text, staring at my phone like an idiot. And when it didn't light up with his messages or calls it kept adding to my depression and confusion.

I kept thinking, perhaps assuming that, I must have done something wrong or maybe said something  unknowingly, which hurt him.

And as much as I wanted to apologize I had no clue where I went wrong.

Finally, after almost 1 month of this torture, I decided to face the truth, to face him. I called him, actually David and fixed up a meeting. As I knew there was no point in calling him, as you would just ignore my calls.

And luckily for me he did visit. When we sat down, I directly questioned him.

"What is it, Ry ?" I asked.

"What is what Elsa ?" He asked as if he was oblivious to everything.

"Us. Our relationship has come down to nothing, Ryan. And I have no idea why.

I don't want it to be like this is Ry. I love you. I really do. And this silent treatment you are giving me, it really is killing me." I said all at once.

"Elsa, I love you too. With all my heart, and you are the only one that I have ever loved this much. And believe me, it's not you, it's me.

It's all because of me I really don't wanna lose you but I can't have you either." He said.

"What do you mean ?" I questioned.

"Elsa, you remember our last trip. It all started there." He said.

"What started there, Ryan ? Don't speak in puzzles." I said.

"You remember how we met through common friends and hit it off immediately." He asked.

"Yes, of course I do." I said.

"I really liked you then, but only as a friend. But once, when me and my friends were off on a boys trip, I was given a dare to propose you.

And I rejected doing it, but when I was given that dare, it made me think.

I actually liked you a lot. Just never thought of you as a girlfriend, but when they ask me to do so, I was just not able to shake the feeling of holding you, kissing you, and claiming you as my girlfriend, as mine.

So I decided that I would propose you but it was not because of the dare, I swear Elsa, I proposed you, because I really liked you." He finally confessed and I just laughed.

"Elsa, why are you laughing ?" He asked, really confused.

"Because, I knew about all this from the beginning. David told me about all this before 2 months or so, after we started dating." I said.

"What ?" Ryan asked.

"Yes, he did. He said that he knew you really loved, rather liked me then, and he didn't want a stupid dare to destroy our relationship. So he told me everything." I said.

"And you were ok with it ?" He asked.

"Well, not completely. But he made me realise that you didn't propose me out of a dare, but this dare, only did one thing and that is made you realise your true feelings for me." I told him what David told me then.

"Well when you put it like that." Ryan said, sounding a little relaxed and his awesome smile returning back on his face, which automatically made me smile.

"I can't believe you made us both suffer for a month for this stupid reason." I said still smiling.

"I really am sorry Elsa. I didn't mean to. But I just keep feeling guilty since we returned from the trip. It reminded me of the dare." He said.

"I get it. It's just funny. I love you Ryan. And I will always love you." I said as I got up and went towards him to give him a kiss.

But instead he pulled me over his lap and brought his lips close to mine while staring deep in my eyes.

"Promise me this is Forever and Always." He said.

"I will love you Forever and Always Ryan Smith." I said smiling.

"And I will love you Forever and Always Elsa Mills." He said, as he kissed me passionately making up for all the kisses of the last month.
