"there are lots of fish in the sea" fish, yes, but someone who will care for me even though I'm gender fluid? That's what I used to think. Kissing pained me. I wondered if the only reason I preferred girls was because of what happened to me. Kissing girls was different. Kissing girls was softer, and different. After my most recent breakup, I didn't know what to do. I felt as if it was all my fault, I was angry, sad, depressed, empty, anything you could think of.
I felt like no one would love me like she did, but I was wrong. Even though I still have feelings for her, I still moved on.
I now have a boyfriend who does not care about my gender, he cares about me.
The saying there are plenty of fish in the sea is wrong. Not every fish will like you, but if they do, they shouldn't care if you are non binary, gender fluid, trans, or whatever. They should not want to change you, and if they did, they are wrong.
You might still be hung up on an ex, but that doesn't mean that you can't be in a relationship, as long as you truly love them, or even just like them.
It took me a while to realize that. It will take me awhile to get over my ex, but I still love my boyfriend.
And besides, you don't need a relationship to be happy.
And maybe someday, you and your ex might get you ex back.
