Accept your flaws and your partner’s flaws. It is not possible to be everything at once, so just accept it and do not try to change them.
Communication is the key to a healthy relationship. Talk things out and build a healthy relationship. This is going to improve the equation you both have.
It is okay if you take time to adapt to things, but change is inevitable. So, take your time and have room for both your needs.
Do things that interest you. Having your own life is important. The other person can help you, but you must do things for yourself to keep yourself happy.
Be yourself. Do not try to pretend to be someone else. The moment you get real with your partner, you take a step towards a better relationship.
