I think that i may be in love with my sister.
To put it blatantly, I think that I may be in love with my step-sister. My mom met her dad about 2 years ago, and got married about 1 year ago. Since my step siblings live with their mom about 3 hours away, they're only here about 3-6 days a month. Back to the original topic, I think I may be in love with my step-sister. And I also think that she does not reciprocate any of these feelings. Yet, I am getting mixed signals on this front, as she also seems to enjoy my company. For example, during summer and Christmas breaks, my neighbor will invite me, my step-brother, and my step-sister to their place to watch horror movies until about 3-4 a.m. When I get tired and say that I want to go back home, my step-sister will say something about not wanting me to leave, and make this utterly pitiful face that I just cannot say no to. Her reasoning for doing this is because it's just boring when I'm not there, but from my view, I don't really add anything to the conversation. Also, every time she goes somewhere, she always invites me to go along.
If it matters, I am 15 and she is 16. Any feedback on my situation is much appreciated. Thanks!
