Is my feelings for him love or friendship? Alittle long but please help me. 10 points to best answer..?

Me and my boyfriend have been going out for 2 years 3 monthes. Me and him have been going through alot. 2 days ago he said "goodbye" and I begged him to stay. I was crying and I said " you can't leave me" he was going to leave. But yesterday he asked me to take him back and I did and then he asked me if my feel be for him are friends or an actual love relationship. About a year ago I told him I didn't know if I love him or not and that's what has been happening for a long time now, us going back and forth about it. I haven't said I love you to him for quite some time cuz I'm not sure. I stay on aim during the night just in case he IMs me. I know ALOT about him and he is someone I can tell everything to. Other people, I have boundries and I am not as open of a talker as I am with him. I wish for us to be in love and spend the rest of our lives together, cuz I want to love him. We have talked about marriage and what our kids names will be. Before this all happened, I knew that I did love him, I didn't question. Now I question alot, not just my love for him but other things. He tells me I DO love him cuz if the things I do. He says he knows for a fact that I love him. He isn't a bad guy. He is a good guy, he is caring and self-less, reallyyyyy super smart great body, want to make me smile when I'm down, wants to keep and make me happy, he loves me.

I just need help

How can I not question that I love him?

Do we seem like just friends?

Are we a couple, boyfriend and girlfriend, and share love for eachother?

Please help me
