i think the most important qualities you need in a partner, is a partner who is CONSIDERATE. Someone who can look at things from your point of view, who considers how you're feeling when things are rough, someone who creates a space for you to feel safe and vice versa.
Your partner coming to you about something you’ve done wrong isn’t a personal attack. It’s a healthy sign they value the relationship and want to make it work – it's a heads up. You communicate, you fix it, you stay. That's emotional maturity. That's commitment. That's love.
