It is good to remain faithful if you are married. Faith and trust are important in a healthy relationship.
I am completely agree.  How long have you been married?
I have been married for 14 years now. We've had our ups and downs, but a good relationship takes work.
Constant work and attention is key to a great relationship!
Compromise an important part, too. It can't work if someone insists on being right all the time.
