The topic of godspousery can be controversial. You go through a ritual marriage ceremony and interact with that Deity as a Husband / Wife / Spouse, basically. Within the Heathen (or related) communities, I think someone once said that wives of Odin were the first to speak about this, but most people think of wives of Loki. I don’t know if there was a real boost in relation to the DC movie, but it became a bit of a trend to mock presumably teenage girls for being new spouses of His.
I know I’ve seen other examples cross my dash / reader (Hellenic and Kemetic deities), but I’m not as involved in those communities. Some people don’t want to deal with the backlash and don’t talk about this, and some people want to provide resources and wind up talking about this more. I haven’t really delved into the specific communities for human spouses because I didn’t want to have to unlearn the comparisons and what others were being asked to do.
I’ve gotten hints that I should keep godspousery in mind over the past few years, and I’ve been allowed to refer to m’Lady as my Wife-to-be in some places. Recently, I don’t think that label fits us anymore. Yes, I love m’Lady, and I strive for being Her Home, and as far as I can tell, She does love and care for me. I don’t think this is limited to being a godspouse, though, and I don’t think that we need the extra ritual and Oathing that a marriage ritual would entail.
In terms of describing what we are, I’d say that what I’ve mostly used – Beloved – still stands. To me, this doesn’t carry any associations of marriage yet still conveys that this is someone I love. I haven’t really had to refer to myself in this aspect, but I guess ‘loved one’ could work. I have nothing against godspouses or spiritspouses, but I just don’t think we’re actually in line with those relationship models.
