hmmm....IMO, you can get married but still enjoy life like singles. I believe both parties must give each other freedom to grow, pursue own interests, make new friends and not feel restricted by each other. If you can share the same interests, all the better... but if you don't share it, doesn't mean you must clamp down on your partner's interests.
Of course, there will be mutual responsibilities & committment to each other and sharing of burdens & problems... but your life partner cannot become a problem or the marriage will be long-suffering.
I think most marriages take a downturn when one partner or both feel resentful because she/he feels the other is not allowing enoughy freedom/leeway or providing something for him/her.
Communication with each other like how buddies would talk is the key to how things work out in my own marriage.
Anyway... I am the cool patient dude and I balance out my more hot-tempered wifey... if both hot-tempered... sure die one!
