My type on paper

Basically I’ve been talking to this guy for a few weeks, he’s literally like my ideal type, we’ve even spoke about what we want. only down fall is, he constantly lets me down whenever we make plans. He can be 100%up for it the day before. I really don’t want to catch feelings if he’s not going to put in any effort, what can I do to get him to sort his act out? If anything 😘
