Break up or stay?

Here’s the gist. I’ve been dating someone for about 2 months, things have been alright but the other night we said I love you to each other, I initiated that but wasn’t expecting a reply of the same.
I have feelings for this person clearly but want to make sure that there’s nothing I should be worried about. So I did some digging (I’ve been hurt too many times in the past to not first dig around and see what’s up.).
First thing I find is their dating profile on the site we met is still active. Ok…not promising…
But then I found a profile of them and another person together like a joint profile explaining they were looking to hook up with a third and to contact them if interested.
The other thing I’ve noticed is, my significant other never asks me about my personal life or family, everything is surface. I’ve also noticed they do what I call parroting our conversations. So if I say something they say almost the identical thing back to me or will just ask me the same question I just asked them while trying to get to know them.
Break up or stay. What should I do?
Break it off
Stick around
