Update:

He has the flu and can wants to meet another day...
I am in limbo over this so I text him back saying;
"Depends on the reason to catch up. U have me in limbo with telling me you miss me, miss us. If you are staying with Lisa then I don't want see the point to be honest. I can't have you stiring feelings up in me and not following through."

I think I may have miss read his intention with the message - but really I don't see how I could have thought anything else than I did.

He replied with;
"I didn't think it was possible to have anything but a friendship, that's what you always said. I do miss you and I do miss us. I just wanted to see you and talk to you. I don't know what I am going to do but I would never start something while I'm still trying to work that out, it wouldn't be fair to either of us. I'm sorry if that's the impression I gave you. I just wanted to see you"

My reply;

"That's why I wanted to see you, for a decision one way or the other. I was happy to put history in the past and try to start something new, be it friendship or more if that was possible. I am in limbo over what you said. Sorry to be hardarsed but if you don't love Lisa but may love me I want to know."

And his reply:
I didn't tell you I missed you becuase I wanted you to take me back, I told you because that's how I feel. You are the only person I could tell how I'm feeling. I can't even think about another relationship until I sort this one out. I can't leave her to be with you. If I am going to leave her it has to be because I don't want it anymore. I never actually thought you would consider a relationship with me again and now I am really really confused"

Finally my reply (SO SORRY FOR THE LOOOOOOONNNNGGG POST BUT NEED TO GET IT OUT INTO THE WORLD);
"We need to talk face to face. If you want a relationship with me you couldn't jst go from her to me. That was NEVER an option. You need to sort out your S**T and we can be friends but you have to be free and clear of emotional baggage from her if we were to try again. I can't promise anything will work out, I've been so hurt by you, but the chance to find out is there if you want to fight for it"

He replied with Thankyou.

So I seemed to have gotten myself into a situation that wasn't really there.. or was it???

Taking a step back and looking at it he was asking for friendship and support... he can't have me support him when he's emotionally unstable about his current relationship... I can't do it. He has made me a crazy woman for the past 3 days without even knowing it - all because he said he missed me...
