<human>: Can you provide a brief overview of the text?

Lady and and I are both 28. I have been dating her for a little over two years now, and marriage is starting to come up. Time to "shit or get off the pot" time I suppose.

We had a drunk discussion on this subject the other weekend. Didnt end well because I told her I was no where near ready to get married. She says she is on a time schedule or something like that where she wants to have another kid soon. She has a boy, who is 8, by another guy - not in the picture. She doesnt want to have a new born when her kid is a teenager. I understand.

Subject got brought up last night when she said she will wait it out another year, and if Im not ready by then we will just part ways. I dont know how this marriage process is supposed to work. I really havent even thought about it at all. Shouldnt you "know" that shes the one to marry even if its a year away?

Factors on why I dont want to.
-Parents are divorced and I dont really see my marriage lasting (shitty mindset)

-I have zero authority over her kid. Ya ya I know its not mine, but if I was to marry her, and I tell her kid what to do or what not to do and she doesnt listen, I could never discipline her kid - rightfully so - but I dont want to be the bitch step dad who has zero authority in my (our) household.

-Right now I have zero responsibilities in my life, I am 28, I can come and go as I please with no kids holding me down and I dont know if I really want to change that, ever.

She is a great woman and has an awesome kid. We mesh well I just dont know if I am ready to take that next step. I am just afraid that if I dont take the next step I would regret it, but I dont want to be forced into it. I dont see why I have to be put on a timeline just because she already has a kid.

Any advice would be helpful. Thanks for the input Reddit.
