Hi I agree with Gr3tta.
Balance is good in relationships
Have you communicated this with your girlfriend?
A few things that can be a detriment to a relationship is lack of communication and enmeshment.
If you have a T have a chat with them about co dependence and enabling that might help.
Codependence means "YOU are responsible for MY feelings"
Enabling means " I am responsible for YOUR feelings"
Both of these together equates to ENMESHMENT.
I know this because I tend to feel responsible for others feelings rather than my own.

As adults though only ourselves are responsible for our own feelings no one elses.
