Is it normal in a gay relationship?

Im a 23year old guy in a 2yrs relationship with a gay guy. Is it normal to be insecure with your partner?Me and my partner have been together for two years and within that timeline i have been working hard and doing my best to reach my goals (architecture graduate). My SO on the other hand has his life on full liberty. No dreams and goals. He's living his life just having fun and stay at home since the day we met.Im so insecure in how he's getting all the fun and i get all the worries in my work, my home, my future and our relationship.
