My mom was more outgoing, by far, about her faith, both verbally and action-wise. I always thought my dad should be more the spiritual leader, but he wasn't. Both would go to church though, just different ones.
Now I feel like I am in the same situation myself, where I get "ga ga" about spiritual things, musically, Bible reading, spiritual book-reading, speakers, workshops, basically anything. My spouse doesn't. Sometimes it seems to be a time-related thing, but other than that I think the most spiritual anything for (spouse) is going to church (will put some other things ahead of church) and claiming to pray and pay attention/think about the messages at church. But at church (spouse) is basically reactionless, and it concerns me many a time, but has sounded defensive when asked about the seemingly lack of interest in it.
When I want to attend, join, or take an interest in something spiritual outside of church I feel alone in it, because I never see much enthusiasm about such things on (spouse's ) part. If (spouse has to miss some services I don't see him/her seeking to find out what they missed It puts a damper on me and I have a hard time wanting to express myself. I go head over heels in love with a particular type music, but I think (spouse) doesn't get into music --maybe because raised in a not-so-musical family?
People of the opposite gender or who I see living more outspoken and active in their faith get to looking appealing, yet make me sad that my spouse "can't " be like that too. I often feel unequally yoked.
If anybody else has been in my position and been able to overcome the lonely, quasi-unequally-yoked feeling, and managed to view your spouse with a more loving and accepting lense, to where you can be yourself in how you worship, please let me know.
