I have come to the realization that my boyfriend and I want different things

I feel that I need to end my present relationship. He lives three hours away and likes the reassurance of having someone to talk to multiple times per day and seeing me once or twice a month. I want someone who is more present and more of a life companion.Lately, he has had a very busy work schedule and I have only seen him a few times in the last 6 weeks. I told him that I can't continue in this way because I constantly feel frustrated and angry and that he is not making the relationship enough of a priority. I also feel it is keeping me from possibly finding the relationship I want.We have been together 7 years. The problem is that I panic and experience anxiety and depression thinking of him with someone else and then thinking I will never meet someone I like. We have gone through this cycle already 4-5 times and I feel it is unhealthy to stay in it, but my aversion to the anxiety and depression I experience upon separation always leads me to reconcile.
