You’ve Given Up Your Interests And Hobbies
Remember when you used to actually have hobbies and interests outside of those your share with your partner? If you’re having trouble recalling that time, then you are definitely too dependent.
It’s fine to do things together, but you shouldn’t abandoned things that you enjoyed doing because you happen to be in a relationship. Not to rain on your parade, but if your relationship were to end, those interests and hobbies you’ve abandoned could help you get through it.
