<human>: I got out of an engagement a year ago and now I'm dating the most amazing guy- and I'm his first girlfriend. It's only been a month and I am sizing him up for husband material. Meanwhile he's saying he could never see himself in a long term relationship and kids are iffy. I had a small freak out and kind of went off on him- even though he did nothing wrong. I've only dated one person before him, so I only know long-term, and I am the queen of commitment. How can I just calm down and enjoy this journey we're on? 

I really like him and don't want to mess this up.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm queen of commitment and it's his 1st relationship. How can I not ask so much of him? Is this casual dating? What is that?
