There are lots of good things you can say to someone you're in a relationship with. I like you. I love you. You're amazing. I'm glad we met. Et cetera. But there's one thing you always want to avoid saying. I don't deserve you, or another variation, You're too good for me. Never say this.
Now if it slips out a time or two, you're probably still in the clear. But if you say it with any regularity, you're setting yourself up for failure. Because say it enough, and they'll believe it too. One day they're going to say, "Hey, you're right." And they'll leave, and your tears will flow like Niagara.
You should only convey this sentiment if you legitimately believe they should get with someone else. Because when you say you're too good for me, you're also saying you deserve someone better. You're saying, "I believe you would be better off with someone else." Is that what you actually mean? Because that's what you're saying. Tell them enough and they'll believe it.
