Every relationship has it's limitations. There are certain things you know you can do and certain things you know you cannot. Boundaries are necessary in a relationship as they do help you to maintain a stronger love life and connection. You won't nag one another or cross the line that can put your lover over the edge. You need to sit down and talk about a few things that are "absolutely not's" and "that's fine" as it allows you to both be yourselves and to avoid having to deal with annoyances and frustrating discussions with your partner. Having boundaries also helps to keep you in check as you won't become obsessive or aggressive. You both deserve to have personal freedom and you need to have a certain level of respect for one another if you want to make the relationship work successfully.
