tl;dr op build a good frame at the initial stage of relationship but fail to maintain it costing him his freedom.

The one thing that is holding me back from fully internalize TRP is that I am scared of conflicts,

I ve observed this characteristic of mine for so long and I could have confirmed that it occured so many times before.

For example, I am in LTR, after reading TRP for quite sometime, i tried to apply it, and it worked like a charm. But maintaining frame in a long run is so hard as overtime, i am getting more and more invested in the LTR itself. And suddenly the IDGAF attitude is no longer there, and I can feel that I am losing my freedom just because I am scared to be in a conflict (nice guy attitude)

I ve been keeping to search for the root of this problem but so far it came up with a futile answer. How do you deal with this actually? I mean is it caused by my childhood experience or something?

Note : i am not putting her on pedestal, it is just that i hate being shit tested and nagged. Even for a little.
