Thank you all for sharing and advice! Part of my problem is I am too sensitive and I am not assertive. I just roll over and take it because I do not like conflict. Changing jobs would not help because like avlady said there will be someone else pushy and bossy.

So I can either learn to cope with it or one of the suggestions was to ask my coworker to show me exactly how they want it done to their specifications.

I'm thankful to have a place to vent and people who understand.
