4th of July

I feel like I'm being a little over dramatic & I'm really not trying to be but my bf wants us to go to our home town & watch the fireworks. it's a super small town, we know everyone, they have a beer tent & everyone's always drunk, it's honestly a good time. I'm pregnant, due in December so obviously I can't participate in those 4th of July activities lol. but my bf wants us to go up & hang out & watch the fireworks together then he's prob gunna hangout at his friends for the night which is fine, but is it wrong of me to be a little jealous bc i can't drink or anything? I really don't even care to see the fireworks bc I'll literally be the only sober person there (that I know personally) & seeing everyone else having fun & letting loose just puts me in a down mood. only bc 4th of July is usually the only time I ever get to go out, I don't even go out for my birthday (which is in October). idk maybe hormones but I'm jealous 😞
