My exWH was controlling. He wasn't just insecure, or had different views on social activities. I'll give you some examples of what a true controlling husband is like, starting from early in the relationship onward:
While dating ( I was a teenager) , he'd chastise me about smiling too much around men, the things I'd wear, etc. I learned not to do these things, because after any event he'd tell me how slutty I was acting, etc. He'd make me feel horrible about myself. He's tell me I was a slut about sexual things I had done before I even met him. He once even got mad because I stared at a billboard with an attractive man on it. It effected my work, he'd periodically stop by, and even in a female dominated industry, he'd freak out if he even saw me waiting on the occasional male client that would wander in. Once I went on a job required day trip out of town. I got back, and he was sitting in the dark staring out the window, pouting and scowling. I never went again.
He never wanted me out of his sight. I had zero girls nights out the whole time we were married. He monitored my time if I even went to the store. We hung out at my house if I wanted to spend time with any friends. With him around. Of course, he'd be charming and cook for us and everything, and everyone thought I was SO lucky to have a husband like that. Or he and I would only go out as a couple.
He'd buy me lots of material things to make my home/prison luxurious. He'd cater to my material needs like buying the groceries, bringing home take out, etc...therefore I 'had no reason to go anywhere'.
Once we had children, he did little to raise them hands on. This was control, because with a gaggle of little kids, where can you go? During the years raising my children, I think I got my hair done once and he threw a fit, I used to see going to the doctor as a vacation because that was the one place, according to him, I had a reason to go alone. The day I gave birth to my son, the nurses took me down the hall to spend 30 minutes in the sitz bath whirlpool tub. He threw a fit and made them come and get me and bring me back to the room because the newborn was whining and it was my job to deal with the baby. He flat out told me over that, a few hours after the birth of my son, "I'm mad at you" for leaving for a bath, and treated me like shit the rest of the night.
Of course, the advent of cell phones made all this worse. He'd keep track of me all the time.
Once I went with a friend to visit another friend in the hospital. He actually checked up on me while I was there. I mean physically came by the hospital and acted like he was just in the neighborhood.
If he thought I had a crush on someone or was attracted to someone, he'd make up stories about them like that they had STDs or whatever, anything to put them down in my eyes. If the guy had a gf or wife, he'd tell me how mad he could tell the gf or wife was at me due to "how I was acting" to the man; he'd even say I'd deserve it if she kicked my ass. Of course in hindsight it wasn't true, but this made it so I felt like I wasn't even good enough to have female friends.
There was one time I went out with my family and my kids to a busy park out of town. He was mad. He kept calling making "jokes" that he was there and he could see me.
He'd tell me things like "such and such saw you at Walmart" or whatever. He wanted me to think even when he couldn't see what I was doing, he knew so many people that he'd hear it.
He'd have the kids tell him what I'd done that day, or ask my kids things about what I was doing. Subtle, but he basically used them to know what I did.
He always thought I was cheating and accused me of cheating. Once, I had a terrible medical condition for months, I could't work for months, and looked awful and felt awful, rarely left the house. Still, he'd accuse me of cheating, and once during that time he came home and without warning lifted up my skirt and smelled my underwear *while I was wearing it* to see if I smelled like sex.
I became reclusive, withdrawn, learned to put on a fake face to the public, nobody knew what was going on. But in the house, I was depressed, a shell of what I should have been.
Of course, as you can see HE was the wayward. When I finally left him, he went bezerk. I unwisely got immediately in another relationship the minute we were separated. I ran literally straight to someone else, because I was afraid of my WH and I thought if I was with someone he wouldn't bother me as much. Even with the "protection" of another man, my WH still threatened to disfigure me so noone woudl want me, kill me, he vandalized our marital house, I had to get an RO, and he told our very young children right in front of me that their mother (me) was a whore.
So, that's controlling. I'm a damaged woman over this, I'll never be totally healthy. And I'm actually now kind of controlling myself, but it's not really control, it's that I have severe abandonment issues, my man stomping out and going for a drive causes me to literally panic. I'm always hyperaware to signs that I'm "not good enough". I need a lot of hands on attention, lots of stability. I've come to the realization that some men are fine with that and some aren't. I have to accept that about myself and simply be with a man who gets it and doesn't mind.
The stuff you are describing, is insecure, and you really just sound incompatible in that she's social and you're not, and you have anxiety that you expect her to accomodate and maybe that's just not something she wants to do. Perhaps neither of you are wrong.
