I need some help on what I should do. I have been doing the technique since October last year. My POI went on holidays with his girlfriend and came back engaged to her. I kind of had this feeling this was going to happen by something he said before he went away. I've been doing PW, BWD, love spell and even there for a bit the rubbing out technique. I don't know where I've gone wrong. There have been many times I haven't felt anything when I did it but I kept going. This last week when I done the PW I felt sad and a longing but it only lasted while I did it, I did have trouble getting him to come to me and I had to call his name a lot. I thought it was just my visualising struggles I have. He messaged me 2 months ago and he asked about what I was doing business wise and then he hit me up with a business proposal, I turn him down saying I was happy with the business I was running but I would supported him because he meant a lot to me. He told me he wasn't looking for business partners but still wanted to buy something from me whether I supported him all not. He never bought anything off me and I haven't heard from him personally since. He even missed my birthday. He has been working on this relationship with her for a while, going to relationship courses and what not and this holiday was to dedicate time to the relationship. Maybe he never had feelings for me in the first place, maybe I was just delusional. I thought I did see little  coincidences. Maybe these technique don't work for everyone. I don't know I'm very confused. I don't if I Should count my loses and move on or keep going. I genuinely only do it once a day now and some times I don't do it at all because I'm to tired, all doing things but he is always on my mind and I have been trying to live as is, like he is already mind. Sorry it's a long post but I had to get it off my chest.
What should I do???....... Please any advice, I'm devastated.
