It is weird to have such vivid dreams of him out of nowhere. Havent seen him in over a year or talked to him in about 6 months. NO desire to do either. Interpretations?
First thing I would say is the usual one: imo, the dreams you have are not 'about' your ex, they are about you.
The next thing is that both times, what happens centres around the ex (which is why it is easy to think the dream is about him), and everything relates to him and what he is doing. This may well reflect your life together. (Certainly it would describe the way I related to my ex; he kept his life and his hobbies, I became 'his' wife. Years later, I am still trying to find who I am, when not in relation to anyone else. )
In the first dream, he is having a good time, while you are waiting around for him. He has been to a party; you are just happy to see him return. Not a very equal balance.

He is younger, so perhaps this is a summary kind of dream. Early days; waiting around. Happy to see him. No life for you apart from that.
In the second part again he has been having a life; you have been waiting. He has been to a party, bought clothes, found some pets (girls??), and some stuff. Maybe this is about later, when you turned from the person who happily waited at home for him into the person who tried to rescue him.
I am not sure what the purpose of the dream is. It is difficult to find you in it at all, because all your focus is outside yourself; you appear to be defined by what you are doing for him.
I have lots of dreams at present about a 'friend' of mine who is very unavailable. He has been a very great emotional support in the past, but now is very busy and more often unavailable than not. I spend many dreams trying to find him or watching from a distance as he disappears somewhere. Thinking about it, I have had these for months, possibly years. Endlessly searching for the person who is never found. And in real life, I am slowly learning not to rely on him, to accept who he is, but look for support elsewhere, from people who do not let me down.
Maybe, looking at yours in the same way, the dream is holding up a mirror to your life. Are you doing these same things with someone else, but not yet realising it? Are you defining yourself by another person, and waiting around for them? Or maybe it is just a reminder of what was, as a kind of 'well done for escaping all of that.'
Sorry if these questions are too personal. Just thoughts, really.
