I’m a lesbian. I have a boyfriend.

I [21F] feel so awful writing this. I don’t know how to tell him [21M], how to let him down easy.

For context, I’ve always liked girls. For years I’ve labeled myself as bisexual, but I feel like a switch has just gone off in my mind, like I’ve achieved some level of mental clarity.

I’ve been dating my boyfriend for two months, and we’ve moved really, really, exceptionally quickly. We dropped the L word a month into our relationship, I’ve met his family, celebrated his birthday and all of the holidays together, and now my birthday is in three days. And we’re going on a trip this weekend.

He’s such a great guy, and I do love him, just not in a romantic sense. I’m not sexually attracted to him, and I don’t know how much longer I can keep this facade up.

Help me, please?
