Don’t talk shit
Or complain about them to your friends. If you have a problem with your partner, you should be having that conversation *with them*, not with anyone else. Talking badly about your partner will erode your respect for them and make you feel worse about the relationship, not better.
It’s okay that they have different hobbies, interests, and perspectives. Just because you would spend your time and energy differently, doesn’t mean it’s better/worse.
Both of you should have an equal say in the relationship. You are a team, and if one person on the team is not happy, then the team is not succeeding.
If you’re really in this together and you respect one another, everything should be fair game. Have a crush on someone else? Discuss it. Laugh about it. Had a weird sexual fantasy that sounds ridiculous? Be open about it. Nothing should be off-limits.
