Don’t be too open in the very early days.
Easing into a relationship is about ensuring that there is plenty of space for the two of you to get to know one another and trust that you’re right for one another. If you try too soon to “make” something more out of your relationship than it already is, premature pushiness can scare them away and spoil what is ‘there’ to be a good thing. Instead, be patient and realize that it takes time to nurture a solid and enduring relationship.
While being honest to your partner is very important, to the point of being paramount, it is equally important that you are honest with yourself. If you overreact or make a mistake, you can acknowledge your error and apologize. If you’re feeling vulnerable or upset, you can sort through your feelings and verbalize them to them in a non-accusing way.
Speak your mind.
Don’t be afraid to make your desires, needs, and opinions known, even when they may conflict with your partners’. You don’t and shouldn’t exist solely to please them. Besides, showing that you are your own person with your own needs, desires, and approach to life will keep them interested in getting to know and understand you as a person. If you’re comfortable with speaking your mind, then they’ll be comfortable with speaking their mind, too.
Don’t create a fake you just to impress them. It might be tempting if you think they’d prefer a different type of girl but usually this is just cobbling together snippets of things said or suggested and you’re likely to be wrong. After all, they want to date you, not some imagined form of perfection. And if you really feel tempted to change things about yourself because they insist that you’d be better thinner, taller, prettier, quieter, whatever, then it’s a good indication that you’re not compatible.
