Do u think i should get back with my ex?

do u think i should get back with my ex? he is telling me that sometimes he is thinking about getting back together he needs to think about that more. our relationship wasn't always a good one. every relationship has its own issues. he wasn't always a dependable boyfriend. but i was still happy with him. we were on a 3 month break. he wanted a break when i didn't. do u think i should give it another chance or let it go?
