Should I be happy with just friends?

He used to be crazy for me, but I ignored him for someone else. Now that he moved on, I feel crazy love for him, but he won't come back to me. I have lost all my dignity. We see each other a few times a week, we make love and hold each other. The other times he took me straight home after sex, which crushed me inside. But this time, he took me to talk at the park afterward where we talked and I cried on him. He held me and made me feel better. I cried about my regret and he said he won't go anywhere he even said he loved me when I said it. But I know he wants me to take it as a friend. He seems like he loves to kiss and hold my hands as much as I do. He starts to hold my hand, not I. I am happy to see him, but the heart is greedy, I want to be his one. I tried my best lately to show him I can be perfect. I get him gifts and never, ever start an argument , I agree with everything he says. Should I just stop looking for more? I know expectations cause disappointment when they don't happen.
