My professor and I rekindled and we slept together yesterday. I have a very jealous ex and I told him that I like someone else, he was deeply hurt so much so he cried (this is the first time I saw him cry) I felt so badly honestly I do but I had to tell him and set the record straight because he keeps coming into my life but calls me unfair because during our university life I had kept harassing him and provoking him for a relationship. At that time he said he had moved on and was sleeping with someone else and I hated that. Fast forward to the present, I told him that we need to stop speaking and stop with contact and he told me I was being unfair to him because now he is attached. Today, we slept together and I lied to him about sleeping with anyone else and I also lied to my professor that I slept with my ex. I feel terrible and I just realized that I am a horrible person and I just hate when people are upset at me because it creates so much tension. I don’t know if to tell any of them the truth but so far I haven’t or don’t plan to. I care about them both I have supported my ex tremendously and he have supported me tremendously as well but he slept with someone first and that really triggered me even though we were broken up. I just feel horrible and I am glad to say therapy is much needed. I even offered for me and my ex to go to a couples therapy session so we can try to figure out something but nothing came of it.
