Do I still have a chance with my ex?

Long story short, I hurt my ex by lying to her about a girl I was snapchatting behind her back even though I told her i wouldn't. It was one of my clients and i wasn't flirting at all. I fucked up and i spent the rest of the relationship her arguing with me about it. But i remained committed to her from July to December. She broke up with me cause I had my client on tiktok still and i didn't even realize it. We broke up and i tried to give her space and she wanted to get back together but i was skeptical becuase she held resentment. We still talked everyday and hooked up and all that and one day I asked her to hangout and she said she was seeing someone. He already met some of her family and they have gone on a couple dates. She wanted to friendzone me and keep me in her life but Im keeping my dignity and am on day 7 of no contact. I'm waiting awhile to reach out to her again. But am afraid that she will still be with this guy. Opinions on what I should do? I already begged and pleaded for her back on day 0 of no contact
