I think that if the relationship is really serious, then everything is important. Of course, in a relationship, there should be trust, attention, a desire to make nice gifts, your attitude to religion and to raising children. Sex is also very important, but if you have been married for 10-15 years, you should always update it. Passion cannot last long. But the main thing in a relationship is a kindred spirit of a loved one. I was lucky to meet my soulmate on the dating site
