Am I (f23) overly jealous or there’s actually something not right with him(m22)?

My boyfriend has just started studying abroad for a semester a couple of weeks ago. We started arguing on a daily basis recently. He’s a social butterfly, loves making friends, boys and girls. He’s a jokester and he just came out of a year in which he was mostly home because he was not feeling well. I stuck by his side. In that year time we only went on a 2 days and a half trip to some city in east europe. He now is organizing those 5 days trips with all of his new friends, boys and girls, to big cities. That made me really sad and upset. He said he needs to enjoy life now after what he has been through. But the thing is that we’ve been arguing a lot because i feel like his way of approaching girls is not normal for someone in a relationship and also he’s said some things that are controversial:

• he said he needs to be in a group with both genders to not be bored and have entertaining conversations
• he said if i say that our relationship is not perfect, girls will get that as a free pass, so i should act as everything between us is alright
• he said that while he was eating alone he thought of inviting a girl friend that lives in his same dorm/hotel to have lunch with him at the canteen (why didnt he think first of inviting a guy?)
• he said that sexual jokes on girls are fine because he makes them with everybody
• he said that he doesnt wanna go on a day trip with only his male friends and me because i’d be the center of attention as the only girl
• he said that if we go somewhere with his friends there has to be at least another girl apart from me
• He said it’s his personality, he’s not changing for anyone

He said that it’s just that i dont believe in friendship between girls and boys and i dont understand because i only have female friends.

I have been going crazy!! Idk if he’s right and im seeing things out of proportion or im right in thinking he’s not treating me right and being mindful of me as his gf.

I need serious opinions and advices.
