Trans Name

I know I said a while ago that I was genderfluid but I don't really think that describes me correctly so I now identify as non-binary trans or just trans.  I present as masculine all of the time and have chosen a new guy name for myself.  I try to keep this blog as anonymous as possible so I won't be sharing my chosen name but know it shares the same initial as my birth name and I quite like it.  I've chosen a new middle name for myself as well which does not have the same initial as my birth name but I'm still working on that one and may switch it yet.  My original middle name was Marie after my grandmother and I've been looking for another M name but haven't found anything yet.  I was thinking of doing Michael which was my father and grandfathers name but I don't really like it and it feels weird because we weren't close.  Anyway I chose the middle name Oliver and from now on I will be referring to myself as such on here.

This seems like a good time to bring up my mother's confusing behavior.  So I started making changes to my appearance and hinting that I wasn't a woman 7/8 months ago and came out as trans* 5 months ago and my mother has been mostly okay with it.  I say mostly because sometimes she's on board and then other times not so much.  It just really makes me wonder what she's thinking.
6 months ago she paid for me to get a manly haircut
2 1/2 months ago she let me order a binder on her credit card until I could pay her back
Last month she made no comment when I ordered some packers and told my dad not to say anything when I made my packer STP in the kitchen
Last night she bought me more guy clothes and a men's toiletry kit
Yet last week when I asked her to call me Oliver (not name I requested) and use male pronouns she flat out refused.  And the week before she said she wished I would be a girl again.  WTF mom.
