Hey there! As title said, I'm curious what people's thoughts are on online-only relationships/relationships not built on the expectation of meeting up?

I'm asexual (ish? I think?) and have a very busy life, between working graveyard and just general.... Life stuff, and as much as I love my nesting partner, seeing her constantly interacting with one(or more) of her other partners kinda bums me out since she's the only one I'm dating atm. But I don't want to really use dating apps since I know those tend to be a) primarily for in-person relationships, and b) full of people who are typically very interested in sex.

I am really interested in making other romantic connections, and if something built up well enough I wouldn't be opposed to meeting them in person eventually, but I just want to know what other polyam folks think of primarily online relationships?
