Hi Alli,
I admire that you're trying to change the negative situation in your life. Trust issues are difficult, I know because I have those too. As Lonlion said, trust your instincts. I find that meditation is a good way to learn to listen to yourself.
Something I have found since getting sober is that I needed to learn to like myself before I could change anything else in my life. Take a little time to be alone with yourself and get to know and love the person you are.
Love, Anna
