IMO - if Valentine's Day is important to you, you should let your significant other know. If it is not and and you really mean that, then he needs to know that as well.
So, if it is important, you need to let your SO know that. Otherwise, you may be setting yourself up for disappointment if you think he can just guess what you want.
I am learning, at this point and time of my life, that we need to be totally honest with our husbands, fiances, boyfriends in situations like these. If we are not honest, we are setting them up for failure and it is not fair to them.
So if you want flowers and chocolates for Valentine's Day, let your SO know in a SUBTLE
way. If you want to be wined and dined, do the same. And if it is not important let him know that as well but be sure that he believes you. Too many women say it's not important when it actually is and that is what leads to disappointment.
Let's face it - all men need a little help or a little nudge in the right direction......
