Still no sex

So it is the last day of June and we still haven't made love. I can't even remember the last time we had sex. Less than a month to go until our anniversary.  I can't even get excited about celebrating our relationship anymore. I feel like I should withhold sex from her once she actually wants it, just because I am so upset and hurt over it. Hopefully, I can muster up enough resolve to follow through with that if she decides to get some.
