Relationships are a lot of hard work. However, it is important to remember that losing yourself too much is never a good sign as you are betraying yourself and trying to be someone you are not. So, what you should keep in mind is that there are several signs which indicate that you have unhealthy boundaries in your relationship.
For instance, you structure your life in such a way that it completely corresponds to the schedule of your partner. What you need to know is that it is wrong as you need to have time to yourself and you do not have to explain that to anyone. Another common mistake is settling for less. Being confident is important. If you know that you deserve more, go for it as that is the only thing which is going to make you happy. Do not stay in a relationship when you realize that it is going nowhere. Do not waste your time. Have guts to end it and move on. And finally, do not go back to a relationship which you know is over.
