Made a mistake with a client

Hey everyone. So I made a pretty big mistake with a client. And I'm not really sure what to do.
I have been seeing this client for about a year and a half. They were one of the first clients I had as an intern. I won't give too many details but when we started talking they asked me about a particular view of mine. I dont typically share personal things but this seemed to be something that they needed to feel matched theirs so I gave a response. But it was not an honest one. Fast forward a year and a half later and I disclosed something that contradicted that pretty heavily. The next session we had together they called me on it. I tried to tell them that my views were not important, that theirs were. And they said I still lied and walked out. I know I shouldn't have done it, and now I'm going back and forth about if I should reach out and check in on them, or just let them be. Trust was a huge thing that we had to work on there. So this may have completely ruptured our alliance. Anyone else had a similar thing happen? Feeling like the worst therapist ever right now!
