Hes so messed up .........?

ok so my boyfriend can make a commitment but he cant make straight answers. idk if that makes sense but hes there whenever i need him but he makes dates big deal and planning them takes forever and he always cancels them. like today, we were suppose to meet up for a coffee and have sex (His idea) and this morning around 9 i got a txt saying he cant make it. i don't wanna dump him but i don't wanna do this Forever.. what should i do?
