I agree with the PPs. I think we get told often that “love is a feeling, and if you don’t FEEL it all the time there’s something wrong”. Not so. I agree that you should FEEL love - but it can also be because you CHOOSE to FEEL love. You won’t necessarily have that ooey-gooey-mushy-gushy feeling every single moment of every single day, but that doesn’t mean you don’t have a feeling of deep affection.
My favourite example is to look at love in action. Let’s say your significant other (I’m a woman so my SO (now DH) is obviously a man) picks you up, takes you for a romantic dinner, and brings you flowers. That’s nice. But it’s ROMANCE. Now, don’t get me wrong. Romance is VERY important. It’s still important in marriage - that’s why couples need to take time for themselves periodically to work on the marriage. But romance isn’t what’s going to keep your marriage going all day every day. Now let’s say you’ve been married for 5 years, the stomach flu is going through the house, you’ve been up half the night with sick kids, you’ve been changing sheets and holding heads and bringing out buckets, and you’ve JUST crawled into bed. All of a sudden your spouse says “I don’t feel so good” and proceeds to lose it all over the bed. That’s not romantic, to say the least. But it’s love that makes you get your spouse out of bed, put them in the shower, change the sheets, get them a bucket, and tuck them back into bed.
If it helps, you might compare it to our walk with Christ. To be a Christian (read: to follow Christ) is a daily decision. We have to DAILY pick up our cross and follow Him - just as we DAILY have to choose to love our spouses. Now, that isn’t always a “conscious” decision, but when the chips are down, it IS a decision.
