All of your replies have been point on. She has mentioned the idea of tattoos but always said she would let me know when she was ready. It's not so much that she got one it's not including me because I thought she would want me there.
The drinking was more of a shock than anything. It started casual but seems more frequent.
I don't expect her to ask for an approval; but to discuss things with me. I'm not wanting her friends to disappear because she needs them as well.
We spend time together but it is spent at home watching TV because she wants to zone out and shut off after work. Again I understand why. I'm not the best with my feelings and I know it's a problem and I don't want to be the reason that she slips into another low in life. Thanks for your responses it is helping me try to figure and muster enough confidence into talking to her about it. She is my world and it's not something I would ever give up on.
