Married people in the house, please advise, Is it normal for marriage to feel boring?

I have been married for 6 years now at the earliest stage of our marriage was dramatic, my husband use to cheat, go clubbing and sleep out.

There is always drama, he will buy gifts for me to apologise, take me out often. But lately he repented from his ways and doesn’t do all that no more. He now lives a triangular lifestyle ie from home to work to church and back.

He no longer cheats, stopped clubbing and hanging out with friends, he is a completely changed man, I love the new him but it lasted just few years, now I am bored.

Married people please tell me Is it normal for marriage to feel boring?

If yes, how do I get over it, please, I don’t want him to cheat, I just want fun back in my marriage.
