Unrequited Love?

The only guy I love doesn't love me back. I feel like the more i try to force my love on him the more he resents me. He'd rather be fwb but I always set myself up for failure thinking I can be content with that knowing I want more. I honestly feel like I won't be able to love anyonelse because I dumped all my love into this one person. Am I the only one who has experienced this special kind of hell😿💀
