Random rant and questions about relationships

Hi guys! I don’t know what this post will be about, but I’ve been feeling weird lately in my relationship and I need some advice.

My bf and I have been together for three and a bit years. When we first started dating, he was very sweet, romantic, but has always been a more negative person who doesn’t show their emotions too much. I am the complete opposite when it comes to emotions.

He is really good at reassuring me, because sometimes we just need that sometimes. But there have been times I wanted to hangout and he says no, or he doesn’t feel like it. And I get that because we’re both doing difficult stuff at university and we’re busy, but he would never do that before. I am also 0% worried about cheating because he goes to an all male school. We are on great terms, too, this just happened once or twice and it worried me

My boyfriend and family are very close, and he comes over quite often. Lately I’ve been realizing a lot more that his negativity is resonating a lot more and my family is noticing. He will come over for family gatherings and dinners, and I notice he sits around, doesn’t help much or talk much. On the other hand, my brothers girlfriend will be there, talking to my parents, making jokes, helping clean and set things up, etc. they’ve been dating for almost 7 years. Even when I’m at his house, I try my best to interact with the family and be my best self. Sometimes I pretend to be enthusiastic and happy around them. Because let’s be real, sometimes it’s just that way😂 but I know how he is and sometimes I wish he would too.

I know that he’s not a bad man, he doesn’t do it on purpose, but I don’t want my family to think he’s an ass...

He’s also under a lot of stress from school which doesn’t help with his negativity.

He just doesn’t seem excited to do much. I want him to act more like my brother, who is sweet, enthusiastic, etc. I have talked to my bf about this, because I have been genuinely concerned about his well being. He keeps telling me he’s fine and that school is just kicking his ass. I totally get it, but it’s hard for me to be as positive as possible around him to help sometimes.

I guess I’m just trying to say that I want him to be excited to be around me, my family, and just about life more, and I feel like he’s just too Comfortable in the relationship and with my family and thinks he’s doesn’t have to try anymore, but I want him to. If anyone has some advice, that’d be great. I don’t really know what I’m asking for, but I wanted to rant.
