Don't know what to feel

I'm going through a divorce .saw a friend I've had feeling for since I was a teenager he feels the same way. My kids are adults and still live with me and their dad they told me they are not coming with me when I move .in with the guy .I'm not sure how I should feel it broke my heart that they said they wouldn't should I just keep in mind they are adults .and I have to do what makes me happy . because they make me feel like I have to choose
