I can provide some general insights on this matter.
If your father believes that your identity as a transgender person is just a phase or dismisses your gender identity, it could be indicative of a lack of understanding, discomfort, or even prejudice. This kind of response is often referred to as "transphobic" or "not accepting."
It's essential to recognize that understanding and accepting one's gender identity can be a journey for many people, including family members. Sometimes, parents or loved ones may struggle to come to terms with a child's transgender identity because it challenges their preconceived notions about gender.
However, it's important to have open and honest conversations to help your father better understand your experience and perspective. It may take time for him to adjust and educate himself on transgender issues. Patience, communication, and providing resources or information about transgender experiences can be helpful in fostering acceptance.
If your father has expressed that he doesn't want to disown you, it may indicate that he still values your relationship, even though he may have reservations about your gender identity. Engaging in respectful and empathetic dialogue can be a crucial step in creating an environment where both of you can grow and learn together.
If you feel safe and comfortable doing so, try sharing your feelings and experiences with your father. Seek support from friends, online communities, or LGBTQ+ organizations who can offer understanding and advice. If the situation becomes challenging, consider reaching out to a therapist or counselor who specializes in LGBTQ+ issues to facilitate communication and provide guidance.
Remember that it's okay to prioritize your well-being, and if the environment becomes harmful or unsupportive, consider seeking support from others who can help you navigate these challenges. Surrounding yourself with people who affirm and support your identity can be essential for your emotional and mental health.
