With respect, I find the idea of getting back with an ex very dangerous, it's bad advice - you should NEVER get back with an ex, whether they are a twin flame, ex-partner or anything else under the sun.

Nothing good ever comes from getting back together with an ex. In fact, it's extremely common for the situation to escalate badly, very quickly. This is especially true for women I'm sorry to say - women DIE when they get back together with an ex, it happens all the time.

If you've done the inner work to heal, that's great. If your ex has done their inner work to heal, good for them (but they are probably lying to you anyway!). You both need to find someone new. Move on for goodness sake!
