Confused and Unsure

[EMMess]

Had a good time at the beach with the family. Spoke to W before the day before and told her that if she was coming with us, that she needed to be off the phone and respect me, no texting in front of me. While on the beach she kept complimenting me as to how handsome I am, and how lucky she is to have someone so handsome as the father to her kids... I responded with thank you's and complimented her as to how beautiful I think she is.

Unfortunately, didn't stay off the R topic, she brought a few things and we spoke about what happened and where it went wrong. So listened and validated, didn't argue but did mentioned that I didn't agree with everything she was mentioning but I wasn't negating her feelings.

I can't seem to stop wanting to snoop, so hard for me, and to dig for answers. I expressed to her that it was a bombardment of hurts that she did to me, first bd, then flaunting how she was flirting and entertaining conversations. All of that did a number to my mental and emotional health.
Have started reading Co-Dependent No More, part of me feels that I am co-dependent due to how I can't seem to stop thinking about her and what she is doing, it is driving me crazy.

As nice as it was to be around her and having fun with her again, but it makes me sad that this person, who I spent 10 years with, doesn't even want to be close to me or sleep in the same bed.
