BF wants time to think about things

We got into a fight two days ago and I said I wanted space for a few days. He replied saying that he agreed and something else to make me respond. So I did. He replied 12 hours later saying he’s not trying to be mean, he just wants to think about our relationship.

The fight was I saw someone messaged him on Tinder and before I even knew about tinder, we had fought about trusting each other. He says he doesn’t use tinder but didn’t really think to delete it since he’s getting a new phone soon.

Idk what to do at this point. I want to work it out, but he’s making me feel like I did something wrong and I don’t think he realizes that.
