Divorced. My fault, and cant move forward

[Mrs D]

On a side note, last night was good. No contact other than texting him to have our son call me to wish him goodnight. Our son called, we talked then he handed the phone to my ex. We spoke for a bit - good conversation. Lite. Conversation ended and off go bed. Called the ex about 1 cause he had said he was going to brinv our son home in the am. He thought he would let him stay and play with a friend for a couple hours, but explained my son had a bday party to go to.

Pulled up to the house to get our son shortly after, honked the horn. My ex came out with his hands up - "you cant let come to the door to get our son?". I have to be honest, i was surprised. Got out. Alittle flirting when I asked if i could use the bathroom. He said no. I questioned him, he smiled and said yes. I noticed he didnt put our wedding photos back up after i took them down friday. Our son and i left shortly after, but there was flirting... dummy me text him later how much our son reminds me of him. Still flirting some in the text, or atleast I thin until he asks if I sent a unanimous message on fb to
