Teen Gothic

I'm planning on having a Halloween wedding and I want to have a good mix of goth music in the reception playlist. I'm fairly new to the scene so would y'all have any suggestions for goth love songs that are about healthy, successful relationships?😂 Of course I already have Lovesong and Last Beat of my Heart but I'm trying to avoid songs like Love Will Tear Us Apart because it's a bit too negative for a wedding. I lean towards post-punk, dark wave, and ethereal!
