AITA For going on a trip without my wife.

Basically me 26M and my wife 24M have been married since August things have been going great between us and I love her a lot but recently we were invited to attend my cousins college graduation in FL in December and because of work she cannot make it. But my schedule cleared up so I talked to her about it and she said she wouldn’t Care if I went. I’ll be going for 5 days because my family wants to show me the area go to the beach and parks etc. Basically my MIL found out and got kinda weird about it, she’s a very traditional person and believes husbands and wives should be everything together etc so going to Florida without is a red flag in her eyes. I talked about it with my wife and whiles she’s jealous I’ll be going (it’s cold where we live) she knows it’s for family and wouldn’t stop me. Just wanted to get others opinion to see if I’m doing anything wrong.
