Is it the right decision to return the things my ex gave me? For my peace of mind?

Problem/Goal: my bf and I recently broke up and I've been thinking if ibabalik ko ba yung mga bigay nya

Context: ilang beses na kami nag break and may mga time na nagbabalikan kami ng gamit and eventually nagkakabalikan din, pero this time wala na talaga kasi natauhan na talaga ako sa lahat ng ginagawa nya sakin dahil Kapatid and cousin nya na nagsabi ng lahat sakin. So rn I don't know if I should give it back to him, ayoko na kasi ng anything na magcconnect sakanya, alam kong iiyak lang ako whenever I see those things na from him kasi ganun din before and eventually ako pa nagask ng balikan noon. I'm also planning on cutting everyone na connected sakanya pero I don't know kasi nagkapart Sila sa buhay ko
