Should i leave? Or am i overreacting

My boyfriend and i have been together since we were 15, we are now 24.. we have been long distance but made it through, i visit alot.. he shocked me and broke up with me in November but then we spent time together in December and decided to work on things. I offered to visit him in feburary and he insisted we work on things first.. then i suggested i visit him again in March and he said we need to keep working on our issues.. im honestly getting tired of pushing it back and trying so hard.
