It’s possibly you are on rebound or just lonely plus stressed about job. It’s possible. But he might be a great guy too. Personally dating on rebound never ever worked for me.

You don’t really know him on any meaningful level. He might be the best man alive but you don’t know him yet. Skiing or sailing doesn’t say anything about him as a person.
Anyone can text sweet nothings. And butterflies… Well you can feel those for very wrong people too

Do you two talk about anything meaningful? Does he have depth to him? Do you know anything about his life? What he does for a living? Divorced? Single? Does he know you just got divorced less than a week ago?

At the moment you have more free time than him as you don’t work. Having lots of free time explains you wanting more texts or calls. Does he work? In many jobs you absolutely cannot text or call during the day. Going hours without speaking or texting is a normal life occurrence. People work and have obligations. Hopefully when you get a job you won’t be as preoccupied with a guy and will slow down

Who really knows. He might be dream comes true. You just need to get to know him better.
