Really want to go with my mom

I lived with my parents most of the pandemic and recently moved into my S/Os parents house with him.

I haven’t seen my mom in over a month. Before Christmas I was going home every few weeks to see them for an hour or so. My S/O seemed fine with it.

His mom, when we moved in let it be known that occasionally my SIL and her family will come when my BIL has work trips, so that my MIL and FIL can watch her two kids while she works. They’re young but my SIL is afraid of them getting covid, even though my MIL is potentially exposed and so isn’t my SIL(both from work). When they come my SIL has asked we quarantine for 2 weeks(MIL and FIL work and go to grocery store nothing else).

My SIL is coming again soon and during that time my mom has asked me to go dress shopping for a wedding she has this summer. She basically told me she missed me and hoped I could come then asked when she’d see me next if I couldn’t go. I know one thing that my SIL and BIL are worried about is anything from a store is dirty, including clothing/yourself(because you went in) so everything quarantines for a few days and you do a full shower(including hair because that’s dirty)

I need to run this by my S/O. Do I even bother? Part of thinks I should but part of me also feels like I’ll have put him in an awkward spot if he feels I shouldn’t go but doesn’t want to tell me I can’t see my mom. I just really miss her and want to see her.
