So, a couple of years ago, I started having feelings for my cousin, however, we hadn't seen each other too much and even though we talked a lot over text we lived on opposite sides of the world. Now, to be with family, me and my mother moved to the same country as her and our family lives. This means that I have seen her quite a lot, sometimes as much as more than once a week. But instead of trying to pursue my feelings, I thought I would try and get over it, and have even had a relationship in the mean time, however, that hasn't worked out and now I find myself right where I started, somehow still with strong, if not stronger, feelings for my cousin. We text each other and muck around as good friends do to an extent, but deep down I want it to be as more than just friends. My friends have seen how we text each other and say we seem almost too close and it seems kind of flirty, but I'm not sure, especially because that's how we've talked a lot of the time, although it feels a bit more prevalent now. I'm not sure what to do in this situation, so any advice would be appreciated. I am 17 and she just turned 20 if age is of relevance. There are many more things I could say but they don't really come into relevance context wise.
Thank you for your help.
