My spouse says that if I’m not in love or actively working on being in love, then it can’t fulfill the “unity of the spouses” part. I told my spouse that I’m not circumventing or refusing unity, I’m open to unity, in much the same way as a couple who is not actively trying to conceive and maybe even don’t WANT a baby, but are open to life and have sex anyway, which is fine. But spouse says it’s different.
I should also add that this is mostly okay with me, i can deal with it and don’t want to make my spouse sexually uncomfortable, as I’ve been systematically pressured for sex before and it is horrible. I just want it on the record that I am not refusing sex at all.
