My ex-boyfriend doesn't want to get back together with me. But he was willing to take me on a trip when I got my period, and he was reluctant to part with me when I left. why

Since I broke up with my ex-boyfriend, why should I tell him when I travel? If a man agrees to break up with you, then he is generally really over it, so don't have any illusions about him! When he leaves, his disappointment is only his guilt for you! So forget it and put it down when you come back from your trip! Start a new relationship!
