I feel like this same effect could apply to most things that are "addicting". When something is taking time away from a relationship, it is most likely going to cause problems.

Things that cause similar problems in excess: Porn, Sports, Friends, Alcohol, Drugs, Consistent but time consuming hobbies like surfing, Startups ...

What I am getting at is that basically anything could cause similar problems, though the exact side-effects could be slightly different because of differing situations.

Growing up in a small surfing community, I witnessed surfing to be a pretty common relationship problem. Many were so addicted to surfing that they wouldn't spend enough time with their families.
