I have similar problem to ignore what is. My guy is not dating anyone but still its hard for me to see him not wanting a relationship with me. And I can be positive for few days but then I get to negativeness as I start to think I deserve better and nothing is changing, basically I see what is. And then I start to think is it better to continue the visualization or to move on? and I go like this for few years now. But today I had some AHA moments which I didnt think about before. And that was is there a possibility that I actually dont want him back? It seems like nonsense but I had this recently with new flat. When I asked this question why I dont want to move to a new flat? I realized there was lots of fear regarding the new place, like last time I moved we broke up (twice that year) and so on. So when I thought about that question why I dont want him back? I felt like the answer is because I am scared I havent changed enough to keep the relationship and also because I am scared that if he is fully back, then he might leave me again and if he does then I will be in such mess that I will never get out of that again. Anyway my point is that with the flat, once I had that AHA moment, I moved in the new flat within 3 weeks, it sort of opened my gates. so it might be the same with my guy, to remove the fear of letting him back.
when it comes to ignoring the reality all we can do is the act if, feeling like the wish has been fulfilled but i guess its normal that time to time we jsut cant concentrate on it anymore and the negative creeps in.
