Dinner and quickie booty calls seems to be the extent of your dating. Go outside of your norm. Mix it up.
Do something different . Go to a sporting event, a festival. Have a fun day date. Start to socialize with other people. Look up fun different things. Do a house project together. Go grocery shopping together (seriously)
See a different side of each other . On our 4 th date M picked up a ton of hardwood with me and moved into my house with me. That said ALOT. The day after we went kayaking and fishing for 7 hours.
Mix it up! View each other in different environments.
