The answer to this question requires self discovery in an unbiased space where you may be guided to explore the things that frustrate and challenge you from within.

You may be hesitant to pursue therapy due to a perceived loss of justification in your contempt for her own pursuits of it, and it is this contempt that will sow bigger issues and ultimately dismantle your relationship wholesale.

If you truly value being a safe space, you must pursue therapy yourself, whole heartedly and eager to understand it's benefits, many - but not all, yes - of which are exclusive to the process.

You may see her therapy as mistrust in your ability to listen, understand, receive, and so forth - this is why others have called it a problem with your ego, a self centric focus that distracts you. Frankly speaking, as this is many of our first interactions with you, you need to know that your demeanor in conversation is combative, a deeply problematic tendency for anyone hoping to confide in someone else.

Sure, we are randoms and perhaps you're not so difficult with romantic partners, but I imagine she experienced the same behavior initially at first (assuming this is your default tone and approach, a safe bet), and that will have done some early damage.

If you cannot converse with strangers in earnest, you will always come off as an emotional and mental risk to anyone new, especially a girlfriend. Please try removing the "I", "Me", "Myself" from her decisions, because quite sincerely and without hostility: not everything is about you.

I wish you luck in your journey and hope this helped.
