<human>: So we have been dating for about six months, which isn't terribly long in the grand scheme of things, but its the best relationship i've ever had, we've never had any problems before this, and i genuinely love him. 

With that being said, his ex shows up out of the blue and presents to him his daughter that he didnt know about and wants them to get back together. He said no of course, because the reason they broke up is because she cheated on him with a slew of guys and then moved in with someone else. I know what youre thinking, but he took a paternity test, and surprise: the baby is his. 

He wants to be a dad now (which i fully support and think is commendable) but she is being very manipulative saying things like she will only let him see his daughter if he spends time with her first, etc. She also insists that i am not allowed anywhere near her daughter for no good reason other than jealousy. I obviously would like to be in this little girls life, as i love my boyfriend and would like to end up with him, making me her eventual step mother hypothetically. 

I dont know what to do, i need advice!! He has tried to reason with her and he doesnt want to take her to court if he doesnt have to but she is making things so difficult for us.

Can you condense the text into a few key points?
