avinash Hi Avinash, nice headline, and so very true. It's not just we who come out, but our partners, families and friends as well.
For your query, this should help:

To your question:
> I love a girl and I love a trans girl. Sexual preferences perhaps matter less for now. Am I really in love with a trans woman and beginning to think of serious commitment with her? Or am I living in a fantasy and just trying to satisfy my imagination? Is it just lust or something more?
Firstly, a transgirl is a girl. A girl and a transgirl aren't different people ? unless you meant cisgirl and transgirl.
Secondly, are you in love? Or is it just lust and a fantasy? Simple answer - are you no longer infatuated with her once you orgasm. If you like her just as much without the sex as with, before the orgasm as after, you like her. And it's not a fantasy.
Ask yourself - Are you with her because she is trans? What if she was cis? Would you still be with her? What if being trans was no big deal tomorrow, not a fetish/kink/something 'exciting and different', would you still find her as interesting?
Read the links, I would recommend. Then think of this - There are many things you will give up, to be with a transgirl like her. You will lose some friends, some family. You will be called 'gay'. Your colleagues will judge you. You may have to rise to her defense everyday - some comment in the street, some guy making a pass etc. It can be exhausting, and you may wonder why you're doing all this. What is the point?
Then she will/may have expectations of you - will you shy away from admitting she is trans to others? Will you ask her to hide her identity? Will you be OK with adopting and not having biological kids with her? Will you be OK if she doesn't visit your family/hers if you face discrimination from them? Will you be OK knowing it could very well on many instances, be the two of you against the world?
Because you know, and she knows, you can just date a cisgirl and have possibly have none of the issues.
If ALL of this is still something you think you would do to be with her, then you've answered your own question.
Hope you find the answers you seek! ?
