<human>: Give me a shortened version of the text

So my partner and I have been dating for around 2 and a half years now - living together for the last year. We get along really well and have the same interests and hobbies, and we hardly ever fight.

When it comes to the future we do have some different ideas. I would really like to start having children in 3-4 ish years, but my partner is still unsure if he wants to have them. He doesn't like planning that far in advance, so when it comes to talking about children it feels really uncomfortable and we don't have a deep discussion about it. I already feel like I am nagging him about it and I really don't want to be that kind of person, but I want to know if he really does want to have them.

Lately this subject is really getting me down. We haven't talked about it in ages, and having children is really what I want in life. I just want him to be able to say either "children is definitely what I want/don't want" so I know for sure where we are headed. I love him so much and we are so great together, but children is 100% what I want in life.
<bot>: Has anyone been in a situation like this before? What do I do? How do I have this conversation with him, without seeming like I am nagging him? Am I being crazy by thinking about this in advance?
