I’m so sorry he is saying that to you, it’s completely unacceptable and my advice would to be to get the fuck out. He is racist and does not respect you. Why couldn’t he find a white girlfriend if he all he is going to do is degrade you for not being fully white. Scum.
He. Is. RACIST. Get this scum out of your life. If he has no respect for your mom being Mexican, he has no respect for YOU being Mexican, which he made clear with the comment about you not being fully white. And I definitely think he would react disgustingly to finding out you’re bisexual. You don’t need him in your life if he doesn’t accept and love you for who you are.
THROW ? OUT ? THE ? WHOLE ? MAN ?
