Should I go to my boyfriend sisters wedding?

My boyfriend and I had started dating for almost 4 months or so now and I still haven’t met his family like parents and siblings etc. they do know of me and we’ve all been so busy with life we haven’t had a schedule to all have a meeting with each other bc we all also live distance apart. I did know about his sisters wedding when we first started talking and now it’s about a month away before his sisters wedding and today I just got told by him from his mom that I am welcome to come if I want but as well u fully understand from this whole time that there already sitting set and they won’t be around to entertain me and mostly focus on their daughter wedding and my boyfriend is a grooms man too so I know he won’t be around me much plus I’ll be meeting a lot of his family and it can be overwhelming for me. I don’t want to feel out of place as I already am from our relationship lol. I am a girly who likes to get ready for things type events making sure I look good give the best first impression to the family. But also it still feels too last minute for me to be ready as to finding an outfit, hair, time off work etc. Plus he might want to stay a few days in his hometown but I have to come back for work… idk… what is your opinion on what I should do. Attend my boyfriend sister wedding or just miss this one out until next time? Either way I’m fine with but I do need to make a decision soon.
