Did i fuck up everything with my crush ?

So i've made a few posts about how i liked my best freind, yesterday at around 10am she sent me chats with my repost (love stuff) asking me who i was talking about so i basicly confessed to her. Good part is that she told me to be patient until she completly forget about her ex (a not so good guy) and that we'll try something together.

Since this day we've been a lot closer and i really like sending tiktoks to the one i love and that what i did. The problem is that i sent a few tts at 1pm, she answered to them with "😂" at 5pm even tho i saw her repost that she did at 2 and 3pm (even stuff from her ex).. even tho most of the vids were love stuff, when it was 1pm i saw her texting her ex and i know how much she like to go with him, break up and repeat.

Now i sent her a few other vids and she still dosedot even look at them. I know that she have a life but yesterday we talked almost all morning long and she wasn't cold at all. I feel like i fucked up everything because of how clingy i am but loving her feels like heaven because i hated the fact that i used to live men. Is there something i could do to fix up things ?
