Should I give him the benefit of the doubt?

My SO is supposed to be coming over to talk and pick up his stuff. He's been saying he's coming over since Wednesday (but to see me) and blames work like he can't make time when I know he can. He made no time for me this weekend at all either. So today I talked to him about his nonsense but over the phone.

So my question is, should I give him the benefit of the doubt and wait for him to come or should I just go over and drop off his stuff?

He lives 45 min away from me and I don't wanna keep waiting for him to drag things out. I basically told him that if he doesn't show I'll go and bring him his stuff and we can go our separate ways because I'm tired of the mind games. I feel like he's been lying to me and probably cheated while I sit home like a fool.
