so lost

I got out of a 3 year relationship in September. We were best friends for 8 years. Just got in a relationship in November. Wasn't really ready for one then, but as days went by, I was forgetting about my ex. I love the guy I'm with, I really do. But I also will always love my ex. My ex is telling me how he regrets leaving me & treating me the way he did & he don't want to ruin anything with my current boyfriend. I told him he's not going too. I miss the life with my ex, but I love the way the guy I'm with now, treats me. The only thing about him is that he is controlling sort of. I don't know what to feel. I thought I moved on.
