Question

Hello Rabbi,
I saw that you answered someone here that you don’t see any obstacle to attending a non-halakhic wedding. I was invited to such a wedding during the Counting of the Omer, on a date when, according to all opinions, one should not get married (between the beginning of Iyar and Lag BaOmer). What would the ruling be regarding participating in this event, from the standpoint that one should not hold joyful celebrations during the Counting of the Omer? (Of course, everything is still uncertain because of coronavirus; it’s possible the event will be held on a limited scale and not as originally planned.)
Thank you!
