The best thing to do in this situation is realize that neither of them are hitting on you. They are both giving you polite reasons as to why they would not date you.
But I never said I was interested in the first place so why go out of their way to tell me they aren't interested either?
It's hard to flop it out onto the desk when your microscopic richard gets stuck in your fursuit
i mean to be fair we don't know these people and we don't understand the context nor background of their relationships so it's not really fair to make specific assumptions
Tell them your a brony.
They already know.
They are both giving you polite reasons as to why they would not date you.
I keep reading this as "two girls are stuffting on me"
for serious op, go with whatever you think is right and let the other down easy.
