They/them

Lately I’ve been feeling very disconnected from myself. I’m not sure if it’s the BPD or what, but I feel very....umeshy (no it’s not a word but it feels right) about myself. I’ve been doing some reflecting and I’ve started feeling like I would be more comfortable being referred to as they/them rather than she/her. But I can’t really explain why, which makes me feel like a poser? It just feels much more comfy. Idk. Am I allowed to change my pronouns and even though I’m not totally sure why it feels right? I’m going to sit with it a little bit longer before making any declarations or anything. I’ve talked with my wife about it and she was very supportive.
