Is my relationship over? Any insight appreciated.?

I've been dating my boyfriend for over 2 years. About half a year ago I moved to be closer to my family and three months after that I've been thinking my relationship is over.

When I first met my boyfriend he was everything I was looking for. He was on the road to a great career, I found him attractive and he was and has always been incredibly nice.

I still find him a little attractive but I feel like it's always missing something. He left school to pursue his passion, and I'm happy for him but I find myself thinking about the future and don't know if there is a future.

I tried asking my friend if she feels just as excited with her boyfriend as she did years before when they first got together and she said that she does.

I find myself getting frustrated that sometimes I have to explain the simplest of things to him or he asks me to solve his problems when he could do it himself if he had the initiative. My dad has always taught me to take initiative. I also feel that he's always telling me he loves me but it's suffocating (i have talked to him about before) and I find him getting more clingy as time passes.

I don't know if it's because I'm focused on my family and other things that Ive pushed this to the back burner but any advice would be appreciated.

I feel anxious to end a relationship because he really is a nice, great guy who treats me right. (Even though I do wish he had some romantic bone in his body, like randomly buy flowers a few times a year).
