Manifesting SP back after I ended things

I messed up and ended things yesterday with someone I reconnected with and was dating for a few weeks (full moon 😵‍💫) My ex came back in the picture and threw me off balance and I regret it now

Im feeling like they won't trust me now. I know I need to change that belief but I don't want to pursue them. They ended things the first time we dated (7 yrs ago) so I didn't feel fully safe with them. Should i tell them this? I want them to come around on their own.

Is this crazy of me considering I ended things? :(
