If you made a mistake talk to them
I see too many people on here that apparently messed up but aren’t doing anything about it. Reach out. Call or text them. Just do it. Maybe they have been wanting to hear from you.
Blocked is the ONLY strong signal to NOT reach out. Any other message you might have been left with shouldnt be the end all deciding factor. Especially if you were pushing them away, you need to understand they said and did what they had to, probably not what they wanted to.
Be brave. Reach out. Dont wait until too much time has passed.
