Backstory:
1 year LTR. Been following RP and MRP since before the relationship started. My girl has always been more on the shy and anxious side and open about shit that's bothering her. I, in turn, am always doing my best to remain stoic, made a point not to vent to her, always keeping in mind to stay on the mysterious side.
Over the course of the relationship she started going to therapy to deal with her anxiety. It also seems she started acting more like me recently and I've been getting a feeling that she's closing herself off.

Question:
A few days ago I offered her my help and laid out a plan to get something done after letting her vent about a problem that was stressing her out. Today I found out that she handled it by asking a colleague of hers to help her after talking to him earlier that day. Got a bit butthurt and after talking about it she told me this:

Honestly, I didn't want to use you for this kind of thing. You're the last person I ask help from in these kind of situations because I don't want to feel like I'm using you. I want to do everything I can to fix shit on my own instead of you being the first person I ask to help me all the time.

Took the advice I remembered from somewhere around here and told her that I'd ask her next time if she only needs to vent or if she needs my help.

I actually don't mind taking care of shit and I like to know what is going on in her life. Kinda hurt my ego to find out she asked another guy for help before she asked me.

Do I come off as a bitch here and is my girlfriend more redpilled than me or is her closing off to me like that a red flag and a sign of something else?
