Will they ever contact me again before I move on?

Me & my Ex broke up the 11th of Nov after 4.5 years and have been NC since except for a small text exchange where they asked me to block them on social media. (Previous posts yesterday) They broke up with me after cheating on me twice in 2 weeks me forgiving them and then they broke up with me the next text message and wouldn't call me or anything and kept threatening to block me when I asked why and all that. They've weaponized breaking up before whenever an issue arrised and they felt guilty about it in order to try and drop it but idk they usually reach out by now and try to get back out with me but in a way that makes it seem like they're doing me a favor/I want to go back out with them. They're blocked everywhere but phone incase of an emergency.

They keep stalking my fb, insta, & snap through burner & friends accounts that i keep blocking but they won't text me.

Idk I really miss and still love my ex I'm usually over my ex's by now but idk this one hurts cause nobody's goals or life plans, vibes or like even sex matches up with mine like they did.

Idk how long did it take for your guys ex's to reach out?
