<human>: Provide a brief overview of the text.

So backstory: I'm a [22F] and my bf [26M]. We've been together for 6months, we live together w/4 other housemates. FYI, this is my very 1st relationship, so I'm not sure where people typically stand at this point in time. Overall the relationship has been pretty smooth and I really love him. But recently I've just haven't been very happy. 

I'm a highly introverted person, he's highly extroverted. So I often don't want to do social activities such as just hanging out with friends. I mean I do hang out with people but for me it takes a lot of energy. Having conversations that I find interesting are difficult. I'm not sure if it's just because that's who I am or I just don't fit in with the people we hang out with. Also, it doesn't help that atm I'm definitely not in the best place, I'm slightly depressed (which does not help matters.) 

Recently I've been feeling more sad and kinda lonely I guess when he's socializing w/o me (even though I often choose to not socialize).

I'm also afraid that there will be further tensions in the relationship with our interests being considerably different. I don't know quite what to do about it. 

I can't tell him to not socialize, but at the same time I feel alone, idnk but maybe even jealous when he is socializing with others. I mean I hate to say this, but often when I do choose to socialize w/the friend group we have (the one through him) I just don't have anything to contribute or just don't find anything interesting. (Does that sound rude?) Instead of socializing I'd usually rather just be watching a show or something. 

I guess, I'm just afraid my negative feelings might escalate. And I'm sure there's something I can do to make myself happier in the relationship. I pretty sure my unhappiness will one way or another rub off on him, whether it be intentional or not. And I don't want it to manifest into something worse and hurt the relationship.
<bot>: slightly different personalities & interests in our relationship, afraid they might worsen. What can I do to make myself not feel left out when my bf is socializing w/others?
