I feel like a terrible person...

I’ve been out of a long term relationship for over a month now. We called off our engagement three months ago. After I got out of my relationship an old friend of mine started talking to me more. On Sunday we went and hung out. I guess you could call it a date? While we where at his house just talking out of no where I asked him to kiss me. I don’t why but I just said it. He immediately responded yes and put his hand around my neck and pulled me in for the softest most passionate kiss I’ve had in a LONG time. Thinking about it now still makes me smile...ugh it’s so soon but this guy is so perfect and he makes me really want things to go somewhere but I feel like a terrible person! I should be mourning my failed relationship but it was toxic and I wasn’t happy...ugh am I a terrible person???
