Sometimes, it really is time to stop looking for signs from folk. Especially people who remain toxic, who remain in toxic situations, who remain satisfied in their toxicity towards you.
Counseling from a real therapist on toxic relationships and separating from toxic people and toxic relationship habits would help you as it did me–and a separation ritual with candles and a bath would help too if you want to do it yourself or have someone who’s initiated do it for you.
You just need help letting those echoes go, that’s all. Ignore the energy waves you think are coming from your ex and focus on you.
Time to move on and heal for your own well-being.
