When they say things will change, do you know what type of change it is? Do they elaborate on it? The term change can be applied to anything that is going on in his life. I’ve found that many psychics say things like this which allows you to misinterpret things. They need to elaborate exactly what kind of change it is.
Also, he might have just thought it was a sexual relationship since it seems to have started that way. I speak to mostly male psychics to get their perspectives of why men do certain things and was told that once you have sex with a guy, you in their mind, you go to the bottom of the list of potential partners. And the fact that he only wants to come over to your house or vice versa instead of going out shows his intentions. Sounds selfish but that’s the way their minds may or may not be wired.
I’m not going to tell you to go out and date other people, but truly get to know yourself; your likes and dislikes, etc, because at the end of the day whether we realize it or not, we attract what we are and not what we want. Peace.
