I generally don't care unless I am reminded and see couples and flowers and cards, also places that advertise the holiday to sell junk.
I think for new couples, it can be extremely exciting on Valentine's day, despite it just being another day. i think by the 2nd or third year of a relationship,
it would lose the excitement and become literally a big annoyance to have to go out and get cards and gifts and flowers, relationships get stale after a while.
Women are more gaga about that holiday than men i would guess, but for a guy I guess it is more pressure to be romantic and not screw up sweet or romantic gestures like
buying or wrapping presents or cards flowers etc
2 years ago i was dating a woman around Valentine's day, i think i slept with her one time and besides that all we did was bicker. I think I forgot it was Valentine's day which offended her, but it was already getting very complicated. Besides only meeting her 2 or 3 times, i thought about her a LOT in the last few years, i thought we were meant to be together, i THINK she is now single because I see she keeps updating her profile pic. I really think we both lost out, because we are both single and still got a long great aside from the disagreements. She also wanted to go out a LOT, which i was noticing and i don't like spending 8 or more hours out with annoying people in public and crowds and uncomfortable chairs
