I really can relate to that situation. I have gone through a pretty similar situation that I got reminded of just those past days. It's not always so easy to tell for outsiders why a situation played out the way it did. I don't know your thoughts, but I can try to reconstruct them with the help of my own story. As I said, the same thing happened to me. The guy just disappeared. I found a new guy I like and we were in contact nearly every day..and then he suddenly stopped talking to me. What happened was that my memories of this other guy came back and I was afraid it would happen again. I think the same thing could have happened to you and you manifested it again by being afraid of it. It's hard to overcome someone ghosting you, so it's understandable that you have linked it somehow to that guy. But I think that's the very reason he has disappeared again. You have two options here. You can say "He is an asshole and I move on". That's a valid choice, but you give the power to him. The second option is to focus on what you want with him, regardless of how the situation looks like. Paint what you want over the drawing of life that you see. He is completely into you, he is chasing you, he can't wait to see you. I think, when someone changes their behaviour without obvious reason it's always because of your vibration. But isn't that good to know? He can also change his behaviour in a good way without an obvious reason.

I haven't really solved it. My life got busy and there wasn't so much time to think about him. I couldn't manage to align with what I wanted for months. Then, maybe a month ago, I started to take the advice that Sam gave on this forum. She told us that she started to make the vibrational relationship with her guy more important than the physical one. I did that and for the first time in months, I was able to feel love towards him. 3 days later, the new guy showed up. He was my path of least resistance and I decided to give him a chance. Since then, I don't longer think so much about the other guy, but I'm sure I would still think about him, if the new guy hadn't shown up.

I think the vibrational relationship thing is really good advice. You can talk with your guy in your mind, you can have all the feelings you link to him without him being there physically, you can visualise whatever you want. If you can manage to make that more important to you than your reality, your reality will change. Don't think about what has happened. The past has no relationship to your Now and your future. There is no point in thinking about what was. Focus purely on what you want and what you want can come fast.
