Ok I haven't posted in a long time even though I check in from time to time to see how everyone is doing.

Sitch is my wife dropped the bomb 10/03 and finally decided in 5/04 that she was done. The divorce was final 12/05. We have one D 10yrs old

I always tried to mantain a close relationship with her, but she was very cold and non responsive for about 6 months after the divorce.
I always thought we could get back together because our issues were a lack of communication. I started a realtionship about 6 months ago with an amazing lady, my ex has bounced from bf to bf.

She called me two weeks ago when my D had an away basketball asking me if we would like to go together like "a happy family"
I'm like OK, whatever.
When I drop her and my D off she gives me a big tight hug and a kiss on the lips.
I thought this was totally out of character and very confusing.
I decided to see if she would go to dinner with me one night to catch up on things, she agreed.
We go to dinner and it was great time. I feel like I need to test the waters so we have a conversation about us and how we changed for the better. It was a good 45 min convo and she tells me we both changed a lot and probably could date each now.
She leans in to give me a hug good night and we end up kissing passionately for about a minute. She then says we can do this again sometime if you like. WTF!
She has me all confused and has stirred up my feelings again just when I thought I was over her.
I decided to go over her house last night to talk about what happened Friday night. I get there and we ended up watching the Oscars for two hours. As I am leaving I asked her if she had a any interest in dating. She replies, she never would have thought she would consider that until recently as she has seen that I have made some major life changes. She doesn't know when she will be ready to pursue a dating relationship but its not out of the question. She said it could be one month or 6 months, she can't give me a time frame. She doesn't expect me to put my life on hold, but now I am all confused.
She is ok with hanging out maybe once every week or two for right now.

I am in a great relationship now, but I would want to be with my ex if I had the oppurtunity.

So may question is, how do I approach this? I feel like I am DB'ing all over again.

I am also feeling like she still wants to date around and if she doesn't find anything better she will give me a try.
