So me and my ex been talking about getting back together and. Stuff. We even hung out. He kind stopped replying sometimes tooo me I didn’t really care but I felt like I bothered him so I told him i feel like he doesn’t wanna talk and that I’m ready but if he’s not then it’s okay. But he didn’t respond to that. but next day he told me happy birthday. After that we haven’t spoken but will like my pics on Facebook. What should I do?
