I self sabotage a lot. Definitely something I need to work on, Whatever mental stuff I have going on is no excuse for me to be a shitty person in a relationship. Regardless of how self conscious I feel but I get in my own head a lot. I get jealous and concerned over things I shouldn't get that way about.

I'm also by nature very competitive? But this is one I've learned to turn into a positive thing, for example: my girlfriend and I are both artists. Although when we got together I was at the end of a 3 year art block. We had a class together where we basically had to do a sketch if a costume design by just reading and imagining what the costume would look like. She drew something beautiful in a couple seconds meanwhile I had barely done anything art related in the last 3 years. I saw what she was doing and thought to myself, "how is she better than me?" Which I IMMEDIATELY realized was a fucked up thing to think.

Since then I've turned it into, "what can I learn from her?" How can I better myself as an artist by picking up technique and discipline that she uses and better myself from that?

It's all about turning your red flags into lessons to be learned. Once you do that you've overcome your red flags.
