Grateful for my dreams of my ex last night via /r/gratitude

I dreamt of my ex last night. Like all night long. I would wake up, realize it was a dream, fall back to sleep, and another dream with him in it would start. Usually he’s really mean to me in my dreams. Usually they’re memory type dreams of me hiding or of him making fun of me. Last night was different though. He was nice. He missed me. We weren’t getting back together, it was as if we were just trying to get along for the sake of the kids. We had two girls together and when we split up they were grown and decided that I wasn’t their mother anymore. So I moved away like I was told to do. Anyway – in the dream he and his wife came to visit me and my husband. It was really weird. The girls, our kids, weren’t with them, it was just him and his wife. Brandy, his wife, was her usual perfect, helpful self. The emotional feelings were strange. We talked, me and him, and I asked how the kids were and he said what they’d been up to since they’re little women now with their own families. They’ve been doing really well he said. I could see sadness in his eyes, not anger and hatred like I would usually see. Not the anger and hatred that I know I deserved to see. Each time I would fall back to sleep the dream would start again but a different scenario would play out. Same basic events, but different conversations. Sometimes Brandy would be in the conversation and sometimes my husband would be there. In the last dream I had, right before I woke up for the day, it was the same scenario , him and brandy here in our house. But this time the girls came over, Ivy was only 9 or 10 in the dream and Annabelle was 5 or 6. They came and told me about their day and I remember wanting to hug them but seeing that they didn’t want me to. I don’t know if I consider these bad dreams or not…. I’ve read that when you dream it’s your brains way of doing its own therapy. I woke up with this strange feeling… hard to describe. I remember the feeling of missing him. After we broke up I missed him for so long, it was so visceral and enveloping. We spent over 20 years together and he was the only man I’d ever loved. The usual dreams I had of him I would wake up feeling grateful that I am far away now. This time it’s like an in between feeling of the residue of missing him and a feeling of closure finally. I feel kind of sad this morning, but kind of relieved too. Maybe my mind is finally ready to accept that I’ll never see them again and it’s giving me the green light to be fully happy. Not that I’m not happy in my life, I am happy. When I notice how happy I am there’s a part of me that feels sad that I can’t share it with the girls. Maybe I can let go of that resistance to feeling fully happy. I don’t know if it makes sense. I’m grateful that i can save this post and not care of anyone even reads it though. I’m grateful for my life.
