I don't know what to do. I am at a loss on how to handle myself and talking with people who don't understand the delicate threads of reconciliation, just cause me more stress.

A short note:
Was married for one year. Was together 6.5 years. We are both 31. No kids. The marriage fell apart because my Ex has an:
EA
Midlife crisis
Wanted to date other women and explore the world
Didn't think he ever loved me and I was the wrong person for him
Didn't want a family with me, wasn't sure he wanted kids (I do)

Flash forward. Divorced Dec 9, 2002. I tried everything to save my marriage and then just let go, moved away from our home, to GA, 1800 miles away, and started my life over. Over the year we have sporadically kept in touch. But I moved on, was dating men, and had just accepted things.

Flash forward to November 2003. He books a plane ticket to see me Thanksgiving weekend. We have a great time. He leaves. My heart breaks. But I still move forward. I go home for Christmas - and see him for dinner. He buys me all these extravagant Xmas gifts, and we talk. He says:

He loves me still
He is happy, but would be happier with me
Realized he wanted a child with me

New Years Eve. We spend a week in FL together, at his request. He had booked a diving vacation and asked me to spend it with him. Again, great time. We talk more. He loves me, realizes it and wants to be with me. Doesn't want to date anyone else.

Here is the PROBLEM:
He is STILL on MATCH.com and he last checked it 3 days ago (I checked this morning and he is still on it)
HE went to a bar with the EA Saturday night and he said another girl gave him her number
He just gave me his credit card number to come up and spend Valentines Weekend with him. He is paying for it. We are supposed to talk and work through things.

I feel by him still being on that dating site and going out with EA, which he knows hurt me, means he is not serious, and doesn't want this. I am not sure how to act, or respond or even what to do.

Can someone help? I need advice desperately.
