<human>: Bit of a backstory while still trying to keep it anonymous. Long-term relationship just ended, slightly from out of the blue- mainly we were disagreeing on the children issue (he wants, I don't) and he felt like he didn't want to continue and get more involved in each other's lives if our priorities don't match. It had come up before, but we never took action like now. Of course, holidays are approaching, we had a getaway reserved, friendly gathering, etc. but that's all bupkis now. We don't want to lose each other as friends, given that our history is very involved and we've grown with each other for a long time. The bottom line was that I've felt strongly against kids, however I am also nowhere near where I'd like to be in my life to be seriously considering it, and I know people change and I didn't deny ever changing my decision... but he wanted someone that knew NOW that they wanted that in life, and I don't. I can't help but feel guilty about this, and of course the timing is just terrible. I'm also not too keen on making time for casual dating, as it's not really my thing and I'll still be living at home for a while. 

I guess what I'm asking for is advice on how to cope. I understand the decision and we do love each other, but he also feels like we've been dating so long (with minor bumps in the road, as with any couple, but we're definitely a good match) that he's asking "what if?" and of course that doesn't make me feel too great either.

Give me a shortened version of the text
<bot>: 5.5 year relationship breakup over being at different stages in life and me 90% sure about wanting to be childfree, even though he's not ready for marriage, and how to deal.
