Confessions: My husband likes to stay in, I like to go out, I’m bored out of my mind

I am married and we have a good relationship with my husband. Part of this is because we are the direct opposite of each other so there is really usually not much friction maybe also because he is 46 and I am 32.  The only problem lies in our personalities which are so different. He is more of an introvert preferring most of the time to read things while I am social and outgoing. He doesn’t refuse for me to go out with friends but he acts different for a few days and sometimes makes funny comments. He doesn’t drink nor dance and prefers to spend time at home. I’m not sure for how long this can go on because I am not happy with him even though I love him very much. I am already getting tempted to seek happiness from somewhere else. Please help.
