Single but Hopeful, Right?

I thought about a lot of things related to my relationship with my sempai. I love him, and I only want the best for him. I understand he has a lot going on in his life, stuff that I just can't help with. The past weekend I considered if this relationship was the best for him and me at this point in my life. For him, he is busy and cannot always give me the time I'd like to have with him. As a response to that, I start feeling insecure and question myself and my worth even though I'd already worked so hard to be happy with who I currently am and what I've done to be happy.

To me a relationship, a title of being "boyfriend and girlfriend" is just an agreement to be dedicated and to meet the standards of meeting/talking a certain amount of time, etc. (plus the physical affection)
Long distance was always a touchy and difficult subject for me. I was always very open to making things work, but the distance between already takes away the physical aspect and if life happens and the time to talk with each other is also difficult to have, then both standards of a relationship are not reached.

He is worth it. I'm in love with him and I still want him to find his happiness.

This morning, I brought up the break up, but after talking to my friends about it, I worry that I may have done damage beyond repair for bringing it up. It's not that I want to break up with him, I just don't feel like we're fulfilling the needs of being in a relationship. Once he's ready, I'm happy to return to this relationship and make things work, but I worry if he feels like I've given up on him, when I haven't! I still want to be here for him, I just don't want to expect things in a relationship when he can't give that to me in his current state and I don't want him to feel like he's hurting me because of this relationship.

I want to be hopeful. That we'll just remain friends and that in a sense he'll work on himself while having me in mind. And for me... I hope that we will try again, the right way this time and enhance each other's lives as a relationship should do.
