Search Results: will we get back together

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?

I have recently been hanging out a lot with a guy in my friendship group. I have started to develop a crush on him. He got out of a 2 year relationship 10 months ago. We are both 21. We got in a play fight in the middle of the street when we were both drunk. And he buys me all my drinks. Ask me if I am getting with whoever I talk to when we are out together. Strangers think we are together.

Our friend is trying to set him up with different people and every time I ask him about it he tells me he isn't interested. I invited him to a party and I got told by him that 2 different people liked him but that he was interested in them. And he was being weird the whole night. Staring at me a lot, being really awkward, looking for me and moving closer to me. I went home for 2 days and when I got back, we hung out and he told me that he was going on a date with this girl. This starts to piss me off. Which I think is unfair. He doesn't owe me anything and I'm just upset because I feel rejected. So I decided to block him for a bit, till I get over this and we can just be friends again. I don't want to be mean to him because I'm angry. So, I think sometime without seeing or hearing from him will help.

Am I wrong for blocking him?
