I jst donk know why my crush (24F) nor me (23M) can let go of each other, even though we try so many times to distance ourselves since it was going nowhere.

I (23M) have had feelings for my friend (24F) for while which I have confessed to her at the end of our tenure. She kinda rejected me with usual reason like I am good frnd of her, tht I am not her type n stuff. But we decided to stay in touch, as frnds, even though we didn’t have to since we had no common connection, which was our office b4. We almost talked everyday but never like we used to b4 I had confessed. Soon I realized I need to distance myself since my feelings for her jst wasn’t going to go away n neither was she reciprocating the way I felt for her. So I did, I perfectly ended our everyday conversation and for almost 4 days there was no contact frm either sides, till she hit me wid a random text. This sorta thing kept happening, like either me or her distancing ourselves n her coming back after 4-5 days wid.
I mean I kinda feel bad when she ignores for days, like I always distance myself by ending a conversation but she leaves Midway n comes back wid sorry I didn’t see the msg. Ik it’s a shitty reason but at this point I realize we can’t let go of each other completely neither can we take the relationship fwd, or am I dumb to think tht idk. So I try to manage my expectations n hope that one day I can move on.
It’s jst been bothering me for awhile thts why I jst wanted to rant to someone. Sorry for such a long text and thanks for reading it through.
