i don't think this is accurate at all. yeah relationships can be "harder" with the wrong person, but every relationship takes work and sometimes it might be hard. that doesn't necessarily mean that it's with the wrong person.
You can’t just give up on someone because the situation’s not ideal. Great relationships aren’t great because they have no problems. They’re great because both people care enough about the other person to find a way to make it work.
Be with a man who doesn't make you feel like relationships are hard. Be witht he man who will communicate and laugh with you. This is a must or it will start to become more of a job rather than an amazing gift.
