You are 32. She is 21. She isn't mature enough to be on your level. Girls under 25, if you aren't having sex with them then they are a complete waste of time, and you are experiencing it now....and now I'm getting pictures of a tattoo she just got. Never. Ends.
She will keep waving her hands in your face saying "pay attention to me, pay attention to me." By texting by calling by sending you pictures of tatoos facebooking you etc etc because you feed her ego and getting attention from you keeps her entertained. The only one not being entertained is you.
Tell her you're not impressed with the tatoo and tell her you are busy and if you have time you will get back to her. Then go no contact, block her on social media and your phone and go date girls who won't waste your time.
