Confused

So my ex boyfriend and I, broke up a week ago. When I asked him why he did not explain. He said it's not me or him. We just need space. We have 4 kids together and was TTC #5 after losing twins. This would be our 3 miscarriage of twins. 
Tonight asking him in we could get back together. He said in a year. That he wants to date... :/ 
Should I wait.... Or should I just move on? Should I fight for him? We been together for 6 years!
