What is he doing?

The guy i have been on and off with for the past year keeps acting like he wants to see me then quickly changed plans. Like last night I was out of town and he asked me what time I would be back and I said around 8 and he said "okay just asking because I have the house to myself tonight and you should come over" so I said "okay sounds good, when?" and then he said "maybe we can I will let you know in a half an hour" then when he finally replyed he said "I'm not really horny right now so maybe not tonight but I will let you know later" and I was sick of him treating me like that so I just said I couldn't because I felt sick and maybe tomorrow and he replied "we will see" what the hell is he doing?
