It’s okay. Things change, people change.
I love this a lot, because I’ve always said I don’t like labels or anything because you can be super straight and one day wake up and realize you’re in love with someone the same gender. Or be gay/lesbian and wake up and discover you are in love with someone the opposite gender. You’ll never know who you’ll fall for one day. And that’s okay and it’s okay if you fall for someone the same gender or the opposite.
