Getting so tired of this 😔

My boyfriend has the house to himself this weekend and he said we were gonna hang out and I was gonna stay the night almost every night. I asked him if I could come last night and he said no bc he was tired. So I was like ok whatever. Then today he said hey let’s go see a movie tonight. I started getting ready and then he said “uh actually can we just go in the morning or sometime tomorrow” and that made me so angry bc I literally asked if we’re still on for tonight 25 mins before he said that and he said yes. He does that a lot. He’ll say we’re hanging out and then cancels a lot. Like 60% of the time lately he’s cancelled on me. But this weekend this girl who he used to flirt with (and she’d flirt back) is in town right now and it’s just so sketchy to me that he’s cancelling on me when he has the house to himself and while she’s in town. Am I crazy or?

He’s talked to like 100 other girls while we were together and got on dating websites when I was pregnant soooo lol
