So recently I bought another tarot deck as her art and vibe just really connected with me, but my interview with her makes it clear that this feeling is not reciprocated. At the end of the interview I asked her for a final message, and she basically said: "I don't trust you at all, you wasted your money on me." Which I expected as in her introduction, she said that she doesn't open up easily to people, but I want to know if there's any way to gain her trust. This question is mainly because I'm not sure if regular tarot bonding techniques would work the same on a deck that just doesn't trust you. Any advice is welcome!

I, 15(F), have been dating my girlfriend, that I will call B, 15(F) for about 2 months now and it's been honestly great, but I don't know if I love her romantically. For context, before dating her, I was in love with my straight(???) best friend, I'll call A 15(F), for about 4-5 years, and I thought I got over her. Now me and B have been dating and it's been great, but things have stopped feeling "right" for a relationship recently. But B didn't do anything wrong, I just don't feel the spark anymore and dates start to feel like a chore more than anything else. And I feel genuinely terrible for feeling this way, and I don't know if it's also because I'm a naturally introverted person and she's been nothing but good to me.

Recently, A's twin sister, G, texted me regarding a kiss that A claimed we had. Eventually me and A talked about it and it was at a sleepover we had a while ago while she was dealing with some pretty tough stuff. She said it was in the morning after she woke up and thought I was also awake, and she kissed me on the forehead. Clearly I wasn't, and she apologized to me for crossing any boundaries, but I really didn't mind it. Then I called her asking what prompted her to want to kiss me and she said it just felt right, and confessed that she had been battling feelings for me for 3 years, but never said it aloud because she just felt so much shame about it. I comforted her and we joked about how she has awful timing, but something about the whole interaction felt so much more... natural than it usually does with my own girlfriend.

I honestly feel like a horrible person, but I really don't know what to do, nor what I'm feeling anymore. I just don't want to hurt either of their feelings because, no matter what, they are both so dear to me. Any advice would be appreciated, and sorry for the long post!

TLDR: I feel a loss of a spark between my girlfriend and something else between me and my old crush/best friend and don't know what to do as I don't want to hurt anyone's feelings because of my dilemma.
