1st love, 1st bf, 1st ex, why i'm still dreaming about him when i'm not even thinking of him?

Okay, his my 1st bf and I'm his 1st gf too. We've been together for couple of years(7yrs), many memories, and trials. But I moved here in the US, then after 4 years I broke up with him bec. it's hard to be in long distance relationship specially his not participating. Our life moves on we dont talk for a while, after another 5 1/2 years of not talking. I kept dreaming about him, plus I have a bf and we've been together for a yr now, and I do love him so much. I called my ex, and he said that he has a gf and he still have feeling for me and it will not disappear, but he didnt told me that his gf is pregnant. My cousin told me that my ex bf, gf was pregnant. I'm not sure what I'm gonna do, he told me to send some pictures, but I don't want too. It's so unfair to his gf and to my bf. But why I kept dreaming about him, when I'm not actually thingking of him? Before we believe that I'm the one for him and his the one for me. But not anymore he has a kid and i have a loving bf... Please help
