My therapist has somewhat frequently moved the time around on me when needed, and also very frequently been late, and once or maybe twice all but forgot our appointment entirely. I used to take it personally, but now I've come to realize he's just a bit ADD. Sitting in his office a couple times the other therapists that work there have told me he's often late. He has young kids, and has told me that basically stuff happens. I think it all turned around for me when I accused him of doing it on purpose to hurt me, and he looked genuinely sad that I was feeling that way. Now I take it more in stride. I realize it's the way he works and I kind of enjoy that I can be flexible along with him. I think he also can sense and appreciate I "let" him do that without it really bothering me. But... You really need to talk about it with him. He may alter his behavior, or he may have an explanation that feels better than the suffering you're doing now. I know the honesty is brutally difficult. I wrote this stuff down and read a lot of it. But, you need to learn to take care of #1, and that's YOU, not him. Taking care of you means sticking up for your feelings. Nothing's wrong with your feelings!! So think about it, but I really recommend talking to him about all of this!!
