New relationship? New rules?

Hey Reddit. So I finally did it. I finally found the girl of my dreams… at least I thought so. So my girl and I haven’t been together that long yet but long enough for me to have fallen in love. Anyway everything been okay for the most part except for last night. She went to a party and ended up staying at the house where the party took place. Am I crazy jealous for not liking that? She was drinking and I know how she gets when she drinks (extra HORNY) and she ended up staying out there. I’m really upset about this. Especially because she’s 11 years older than me. I’m 32 and she’s 43! I feel like she should know better? This isn’t her first relationship? I’ve tried talking to her about it but she takes no accountability for her actions and she really doesn’t care how I feel about it. She’s making me feel like I should have no feeling towards this situation. Am I actually crazy or would you guys be okay with your girl staying out and not going home?
