18. Get Flirty Again
You can't expect to get your butterflies back if you don't flirt. Bring back that slow-melting feeling by taking the initiative and getting flirty with your partner. Leave a saucy note in the kitchen for them to find if you leave first in the morning. Send them "thinking of you" texts during the day. If you leave them at home and go out with friends, take two seconds to tell them how excited you are to see them again while you're ordering drinks at the bar. Compliment them while they're around, and tell them what you appreciate about them. The spice in your relationship won't just magically appear — you have to pepper it yourself.
