There’s a guy???

So I’ve identified as a lesbian for a while but then this guy started to show interest in me and I ended up maybe developing feelings for him? Except I knew him before he started showing interest in me and I never even noticed him beforehand. But now I don’t think he really likes me anymore but I think I still have feelings for him? Any advice on where this puts me? do I just like the attention or do I actually like him?
