The comment above is a half serious joke, but you do seem rather desperate for the approval of your partner and their validation. This isn’t totally healthy, and on one hand can be suffocating potentially, but can also be abused by a bad actor if you happen to date one. And those kinds of partners can sense and prey on that part of you.
I hope you have some positive friendships and relationships to help offset whatever is driving this feeling in you. In a perfect world, I’d say speak with a therapist but who can afford healthcare nowadays.
In time I hope you feel happier and more comfortable just being you, regardless of being with someone. Being able to find self worth solo makes you much, much more rounded as a person, healthier, and ultimately a better partner too. Good luck.
