Also that is called "homophobic" with one word.

That's actually wrong, humans have the right to date whoever they want, even if they have different beliefs, likes, and, most importantly, even if they're the same gender. Also, by saying what I said in my previous comment, I didn't mean the opposite, I meant that, it's somehow, not liked/accept by the person who was broken up because of sexuality to see their crush liking a male, when they're female and they have said that they date only girls
