I broke up with my boyfriend of 2 years in September when I moved to college. It was a horrible relationship, he showed little to no affection, was abusive and just generally not a great fella. In November I got into a new relationship with a guy who is the complete opposite, the only difference being he is very social whereas my ex wasn’t. I was essentially his only friend and now I’m encountering a new relationship scenario with feelings of jealousy and insecurity due to my boyfriend’s social life. I overthink little details. In our friend group one of my best mates is this really funny girl. I love her and she makes the whole room laugh. I noticed when I’m sitting in a room with my bf and our friends, he tends to laugh at everyone else’s jokes and especially focuses on her for comedic entertainment and then when I pipe up he seems to be the only one who doesn’t find my jokes funny. It’s the opposite when we’re alone though and I can’t help but feel a little insecure he finds her better to be around and generally more funny than me. It’s the same, say he’ll give up his seat for other members of the group but when I ask he jokingly goes “no F off” and we laugh about it but it still feels off he doesn’t show the same chivalry to me, or is this a mark of how close we are to each other compared to everyone else? 
I also get incredibly insecure that he’s still friends with an “ex” back in his home country, especially since she doesn’t respect his boundaries when he’s there. He treats me 100 times better than my ex did but I still can’t help but feel insecurities due to him being a friendly person and a people pleaser. The thing is I know I can discuss all this with him but instead I chose to leave the room and go to the bathroom, typing out and ranting this message instead of being honest with him. I would appreciate some encouragement.
