Many possible reasons (fear of being alone, skeptical of a future or better relationship, trying to work things, etc.) and I hope such relationships aren't common.
Incompatibility and financial problems are probably the only relationship killers, the latter being curable and the other not lol.2

Because they feel that they can never have another relationship after the ones they're already in. It's low esteem issues, abuse and lack of assertiveness. They never had the ability to really leave a relationship that was sexual, and that is what ties and binds people. That is how dangerous premarital sex is. It is used as a weapon to hold you captive spiritually, and the person can be used emotionally because the one who gave out the most are often the ones who emotionally invested more. Then you have cases where they don't have a good reason to. Relationships aren't always about being happy. It has its ups and downs, and sometimes you have immature people who just doesn't want to change or try to make their partner change. Overall, we are responsible for our OWN happiness. It is not our partner's job to provide that, though they overall should if that is what they want by showing you how they love you. That should make you happy to be with them in the first place. But if you're one of those unsatisfied people, then the issue is you as a person, and you can't blame your relationship issues on the other if you can't even communicate.0
