My girl wants to try titty milk but I don't

So I asked my gf about a month ago if she would want to try titty milk and she said yes, so I send her my YT tutorials and what not and she watched them and told me it was funny. Ever since then she has been really adamant about getting pregnant and I told her I didn't want to get pregnant soon and she told me that I'm not ready, but then she said it's fine she will get pregnant and get boyfriend and get him to get her pregnant. And then I told her she will have a new man and boyfriend by then and she said yeah I will and you won't be the father of my child. We are very close in age but I am 23 and she is 22. I told her to get a new boyfriend and have them be with her and she said that's fine because I'm just like my mom. I am a good guy and don't fight with anyone and I have a great job. I told her to get a guy she likes better than me and she said oh really well then I will. And then she said she will be single for a little while so she can get herself together but she wants a baby. I told her I don't want titty milk and she said you will when you taste it. I told her I don't want to taste titty milk and she said it's good. Then I told her to get a guy she likes and she said I like you but I don't like you enough you are more of a friend. I told her to get a guy she likes and she said I like you. Then she said maybe I will be with you because the guy I want to have kids with is 2 years older than you and he is not ready right now.
