I wouldn't read too much into his weirdness. like you said, he was tipsy, so everything he was doing would be overexaggerated.
We already know that he must of had a not-so-good convo about you with his mom, and it's quite possible with your SIL too.. especially since they could relate in some ways. Which is OKAY. you've vented to your own mother about H, and boy did she want you out of his life right? it might not be fair, but they are his family, and it is easier for him to vent to them probably then to go to you...obviously (meaning, all of us do the same thing). So I'm sure his mom and sis are just pressuring him to get it over with and he's just not sure what he wants (especially since it sounds like he's wanting you more and more lately), and he's probably afraid to stand up to them or something.. and afraid of the whole awkwardness if you were there.
But really, who cares about that. if you guys get together again, it really needs to be up to your H to set things right between you and his family. But right now, it's about you guys.
I'm almost sensing that your H is putting you up on a pedestal. well, like he's dating you all over again. you know how guys are kinda scared during that courtship time, cause your just this "wow" kinda girl, and they're afraid your gonna say no, and they wanna make sure they say the right thing, do the right thing. just my impression. I would take it all as good in my O.
I'm kinda glad that you had some concrete plans on the night he wanted you to come. I think sometimes it will be good for you to break off a plan here or there, but right now he needs to feel that "want to have you with me" feeling.
So glad your feeling better too!
