Late boyfriend. Don’t know what to do.

Anne

I don’t know what to do. I’m scared to mention it to my boyfriend because we have never argued, we’re always so happy. And I don’t want to start one. But sometimes most times when we make plans like he’s coming over to mine Or he’s driving over to come and get me, he takes a while and either doesn’t message me till last minute, and then says ‘ sorry was doing something, or sorry just got to do this or go here first.’ I ignored it at first but now it’s just happening all the time. Please help.
