Is it normal to stop yourself from loving someone?

I am so annoyed at the fact that my ex is trying to refrain from talking to me and being with me because its "the right thing to do." We have been through a lot in the last few months from breaking up to talking to seeing each other then getting back together then breaking up again. The reason for all this is because its completely wrong timing. It sucks so much. Its all his decision but I get it its wrong timing but I was still willing to work things out. But what annoys me is that it was obvious he missed me, and he wanted to be with me but he even said that its not healthy for him to continue being with me because we;re too far away from each other, he has a lot going on his life so the best thing to do is to split. When we first broke up, the kept in contact with me a lot though and I told him that it wasnt appropriate because hes the one who wanted to split so why is he talking to me? He noticed I was right so he said hes going to try to not talk to me whenever he wants to and eventually hell get over me. Well if he wants to talk to me and be with me then why can't he be with me?? I get all these obstacles in the way but god I just think he thinks too much with his head. Why are you trying to stop yourself from being with someone you wanna be with? cause its healthier? Ugh obviously whats supposedly "healthier" isn't making neither of us happy. Like why cant we let ourselves be happy?
