Need outsider opinion

I was married not to long ago. Still am legally because I'm getting the money together needed for when I turn the papers in.

My ex and I had a strained relationship. We both cheated. We fought a lot. He would verbally abuse me everytime we fought. Especially when he was drunk. He has a drinking problem. Anyways everytime I felt neglected or we had a bad fight I would turn to this guy I've known for 11 years to talk to. Sometimes we would send nudes and sext. I never physically slept with anyone other than my husband during our marriage but you know pictures and sexting is still cheating.

Anyways. I moved out and lived with my sister for a while. Was really depressed and started to develop a relationship with one of her roommates. I really like this guy and He's pretty great but since we started working together and are trying to not spend every waking hour together I've been doing a lot of thinking and I started thinking about that guy I know again. I've had feelings for that guy for the past 11 years and we have never gone longer than a couple of months without talking.

I feel like a total bitch. I don't want to hurt this new guy. At first I thought it wasn't a rebound thing but now I'm thinking it might be.

Please give me some advice. That's all I want. No nasty comments either please. I do that to myself enough as is.
