had a nightmare last night

so last night I had a nightmare that my ex boyfriend died. I remember feeling so emotional in the dream, I felt shocked and sad and confused. it didn't just feel like a bad dream, it felt real. like he was actually dead. I was so relieved when I woke up and realized it was just a dream. we haven't talked in about two months. when we broke up I always assumed we'd stay friends but he kinda got distant after the breakup. I was sad about that but I tried to be understanding. now that I had that nightmare, I really feel like texting him. just to let him know that I still care about him and love him (not romantically) but at the same time I hear people all the time saying not to text your ex and that its best to move on so idk. I just wish I could hug him. even tho we broke up and had some bad times, I still think he's a sweet person and I do care about him. he was there for me during lots of good and bad times in our time together. I just wanna tell him that I appreciated our time together.
