Since everyone is sharing their story let me share mine too.
My first cousin lives in another place and growing up we would only go to that place once a year for a month. So this complete love took around two years. First year I told her that I like her ; Im such a shy person that I had to tell her through writing a message on her phone. I honestly did not know what to expect back as I have never done this before. Surprisingly she said she likes me back. ( It had such a good feeling to it, I dont how to say it). So we had to leave two days later with not much said later on and came back. However throughout the year I didnt really think about it too much. The next year we go we dont talk about it much, not at all infact till the last week of our holiday. We went on a holiday with her family luckily. However throughout the whole month she had been asking for my photos but didnt say why. Every time I ask why she would say she wants somewhere private to say why. So before we talk about anything at all I had a dream of marrying her. Now look at this coincidence. The next day we go to the beach. I tell her to come with me to the sea. While walking their I told her to tell me as it was kind of private now. So we go into the sea together and she tells me she has been thinking about me the whole year and wants photos of me to look over when she misses me. (Long story why we cant message). She then goes on about how every night she wants to grow up and marry me and grow up together. It was in the sea and it just felt so perfect and romantic. So she then asked me if I had the same feeling toward her, and I said yes of course I would want to grow up with you. We then had a slow walk back to our sitting place and had lunch. The next day because of my annoying arse uncle we couldn't say goodbye properly and had to leave and go back home, till the next year. This year when I see her I would just want to talk to her for hours and hours as the last two years we didnt really have the right time and place. Ive never really fancied a girl but ever since last year I would just think of her everyday.
Thats how we became together. I started the love very slightly but Im suprised how confident my cousin was towards me. Which is a good thing as she is comfortable with me.
P.S. I want to thank the whole internet especially this forum as it really helped go forward as I always thought cousin did not get married, but because of this forum I couldnt care less about her being my cousin and I have all my emotions to her. Also before I was very anxious about people thinking about me ( It was my brain not me) but growing up thankfully I have grown out of that. And when I think about people's opinion about my marriage, I go to myslelf " I dont care about what they think as long as we are happy" thankfully.
