I'd pick a guys old hoodie over a new piece of jewelry. I'd pick cuddling in my bed over a fancy dinner. I'd pick a cute goodnight text over a bouquet of flowers. I'm in it for the relationship, not the materials.
Things not to do when dating a girl with anxiety. 1 - do not wait hours to text her back, thus leaves room for her anxiety to kick in & her mind to over think. Over thinking kills her confidence & jeopardizes your relationship just based on what she is thinking. 2 - do not ever let her think she is unloved. Whether it's a simple goodnight text or a random compliment, these little things put a person with anxiety in a more relaxed state. 3 - do not poke fun at her illness.
