Would it be a bad decision to come out

Hi! :) I'm new here. I'm Alex (like the lion), just turned 18 and I'm a trans boy.

So. I've known I was trans since I was 12. The first person to know was my partner. And then the whole world outside my house.

I'm super proud to be trans. I love myself. And I express myself outside, just not IN my house.

I just started college, and the first thing I did was file a petition to change my name (I haven't changed officially, since where I am costs money)

They changed it. And I'm very happy... But, what now?

I KNOW that I don't need to and I'm not obligated to come out to my mother. But my aunt — the only one in the family who knows I'm trans — keeps saying (kinda pressurizing) that I need to. That family is family and I should tell her.

I would tell my mom openly, the problem is that she is very divided on this subject. She says she accepts trans people, but other times she makes jokes about it. That makes me confused.

I just don't know what to do. I don't have any trans friends to ask for their opinion so I decided to ask people who have had similar experiences to me here.

:D thank you for reading
