What does he mean with that?

He ment, that after you left him or he left you, he felt bad whenhe left you or reverse. Or he thinks you two can't be together.

Dayum soundz complicated. He was shocked by what you said cause you had like an arrangement going on which made things a lot easier you know less arguing etc etc. Then you said the forbidden # WORDZ lol. If he said that it hurts that must mean that he can't handle getting back with you like that meaning all your guyz problems from before could make things difficult compared to the easy arrangement now. DAYUM MUCH RESPECT TO YOU if you made him say that to you then chances are he still has feelings for you but doesn't want to mess things up. All you can do is mediate with him if you ever get to talk to each other. JUST BE STRAIGHT UP and ask him he wants to give you guys another chance I bet you he does but too scared jst in case you don't want to HONEST men can be strong and all that but emotionally a woman can bring them down lol I know TRUST ME. But it depends how you want things to go

Well from what I understand. If he's your ex. He doesn't want more than what the two of you have already. You gotta remember the boundaries. He doesn't want the emotional part. That will just set the both of you up for hurt and probably mostly you. So to avoid the pain. Keep it simple. He just wants to be friends "with benefits".
