<human>: Provide a brief overview of the text.

For her own personal reasons, my ex broke up with me about 2 months ago. Since then I've started spending time with another woman. We've only had a few dates and nothing serious has come of it. 

My ex and I had big plans for our future, and everyone saw us as an old married couple. We were both incredibly happy for a long time. The last leg of the relationship went downhill however, and was filled with constant arguing, manipulation, guilt etc. I never thought of leaving her because I held onto the dream of our future, but now I see how unhealthy our relationship had become.

She ended the relationship and I was crushed. After a while I realized that much of the guilt and sadness that I was feeling near the end had lifted and things were getting better for me. 

The woman who I am seeing now is amazing. She is very goal orientated, and knows what she wants out of life. These are things that very much appeal to me, and I could see a long term commitment in our future.

Recently however, my ex has been trying to get back together with me, and a part of me wants that. It would be so easy to jump back into our old relationship and continue on how we were. Two things are keeping me from telling my ex no, 1. I feel guilty when I'm with the new woman and I don't know if that's normal. Don't get me wrong, she makes me so happy to be around, but I feel like i'm doing something I shouldn't be. 2. I know she would be destroyed if I tell her no, she's one to react very violently and dramatically, and I know that she could cause injury to herself or other people.

Where should I go from here?
<bot>: My ex ended our (very unhealthy) relationship. I've been seeing another woman (who has her life all put together), my ex wants me back and part of me feels like I should because of the life we planned together.
