It does sound like you had reason to be concerned. Having someone just get you, and you them and all things jiving and meshing and making you feel comfortable are important to many. I'm sorry you are feeling sensitive about it and understand. I once broke up with a guy who I worried for years I'd made the wrong decision. I loved everything about him but I did not feel a secure future with him (he was a very talented but struggling musician/singer songwriter and guitarist). But I went with my gut and it turned out for the best. You may end up getting back together someday if you stay friends.....anything is possible. I hope you do find someone who makes your heart sing.
