It's half true.
For me it's obviously. But I understand that it isn't obvious for everyone. Why do I think like that ? Because if you're happy and your partner too it's a really happy life. However it depends on you and your partner. It's impossible for your partner to be happy if you aren't happy and most stupid it has hope that your partner will help you become happy person.No. firstly you need to be a happy person after your partner also has to be happy. My thought if you're unhappy you can't become happy from happiness another person. And you need to let her(him) to be free person.
