Love isn't just a feeling, it's following through on the feeling with action. You married your husband, you dated him, got to know him, went through a marriage ceremony and stay with him. Presumably you do things with him now, "live" life with him.

The obsessions are just feelings and only expressed on your part, in your head; there's no reciprocal action, no "proof" of the love on your or the others' part. Real love is never one-sided, but requires the loved one to share of themselves so the lover can get to know them better in both words and action. Just looking out of one's own eyes and liking what one sees is not love, but interest.

"He looks good!" is literal but has to be followed up by exploration to see if he really "is" good for one's self. The other has to 'prove" their goodness, deliberately on their part, to you. You, have to explore the other in all relationships, not just what you see/feel/sense in yourself. I liked how my husband treated me when we were dating but I looked at how he treated his mother, my mother, his ex-wife, other women he worked with, etc. before I was satisfied he "treats women well".
