Should I keep it going or cut it off??

So the short version is that I went through a heartbreaking breakup this year. It’s the first one that has left me truly devastated as I thought I was going to marry this guy. Trying to bite the bullet I decided to try dating again to help move on. It wasn’t right away, I let time pass. Anyway, I met a guy who has a lot of the same interests as me. Our conversations are great and I’m physically attracted to him. But even with those, whenever he kisses me I don’t get that “over the entire body” feeling that I had with my ex. Does the absence of this feeling mean I should just cut it off? Or should I give it more time?
