My relationship with my advisor did not end the best. He took months and months to get me my thesis edits (I am currently finishing my 5th year as a Master's student because of this), and I ended up having to involve the department chair and dean to get a response. I was also made the leader of our project after other students graduated or left with little to no guidance, so there were many mistakes on my part because I didn't know what I was doing and he wouldn't help me, but got upset when I asked other faculty for help.
Last time I asked him for a letter of recommendation he took so long to respond to me (despite me asking/reminding him about it daily) that the job closed and a person was hired before he even got to it. I don't feel that I can ask other faculty members because he would find out and get mad at me for not asking him, whether he would write me a letter or not.
I am looking at potentially getting a Ph.D., but they typically want 2-3 letters of recommendation. I am not sure who to ask at this point. I know I could have done better, and I have good relationships with other professors, but I feel that I can't ask anyone at this point and I am struggling to get a job that isn't seasonal/temporary.
Does anyone have any advise or suggestions that could potentially help me?
