you need to find a hobby. maybe start working out, some type of sport, something that will challenge your body and mind.
regarding your relationship - one thing you can do with him is work out a schedule for the both of you to go out. it could be on friday (or any other day) nights, each time going to a different place. e.g. the beach, movies. one day going where he likes to go the next time where you would like to go. or stay home and watch movies together.
