In order to answer this I would require a lot more information to give a helpful response. However, what I can say is that I am of the opinion that a lot of people expect too much out of their partners these days. My general personal philosophy on relationships is that our partners are there to love us and, if we both agree to the terms, to provide us with certain psychological needs. However, they are not usually there to provide us with adventure, to reinvent sexuality, or to take us traveling/buy us shiny things.

Still, I think that sometimes the basis for a relationship means that you were seeking certain things with the relationship when you sought that person out and if they're not providing those things (or are unable) then it may be time to discuss the possibility of seeing other people or coming to a new agreement with each other entirely. When it comes to me, I personally like relationships where I am simply free to be myself and the girl I'm with is free to be her - no pressure, no demands.

My favorite thing to do as a couple is probably to kick back, watch a movie, have sex, sleep, and then follow all that up with an amazing breakfast in the morning. It may not be adventurous, and sometimes the sex even gets skipped, but it has a therapeutic quality many people in modern life tend to miss out on.

Hope this helps and do ask additional questions and provide additional details if you feel I didn't answer what you were looking for!
