Good questions!
First of all, let’s put some perspective on this. A guy you dated for two weeks, ten years ago, stays in touch with you off and on. He’s recently contacted you and told you he’s living with someone.
He’s probably contacting you because he’s interested in you, but after ten years of mostly no contact, or mostly contact as a friend and/or a fantasy girlfriend — someone he thinks will save him when no one else is right for him — he’s just checking in to say hello again, and to make sure you’re still there, not because he’s going to do anything about it — just because that’s what the two of you do: check in with each other periodically.
Now that you’re available, he isn’t, so don’t tell him how you feel — he’s not available, and if you think he’s really moved in with someone because it’s the thing to do, consider that you might one day be on the receiving end of that moving truck, moving in with him because he thinks it’s the thing to do — not because he’s committed to you in any really meaningful way.
I know you’re looking for a new relationship, but my advice is to knock on doors that are open — not the doors where guys are already living with someone. Make things easy on yourself. 😀 You might get a lot of good advice from reading Think & Date Like A Man, [url]https://www.askapril.com/relationship-dating-advice/think-and-date-like-a-man.html[/url], the book I wrote for women who want to find, get and keep Mr. Right!
