Is it possible?

My husband and I have been separated for over 2 years (married for 2). We have 2 children together.
Our separation was for quite a few reasons. He worked away and I was a stay at home parent. I looked after and dealt with our investment property (with really bad tenants), I was dealing with building our home (I dealt with all correspondence, paperwork, chasing up), did everything for the kids with no help plus keeping the house hold together. I felt like a secretary and house maid more than a wife. The stress took its toll badly on me over time.
He drank a bit, which made his moods swing.
He also messaged a friend while we was away telling her inappropriate things. I found out because she messaged me the conversation straight away. I was hurt, upset and became really self concious.
When I confronted him, he said he felt lonely being away and had drank a bit when he messaged her. I forgave him, but it hurt.
I started to go out drinking when I could which he didnt like.
When he lost his job working away, we had so much debt, and I was left t to deal with it all.
I wasnt perfect either - I slept with someone else. I just wanted to feel wanted. I told him. I made no excuse for what I did.
The end was horrible. We hated each other.
I decided to leave.

Fast forward to now, We both rent and have jobs, our arrangements with the kids work well. We still talked while not together and helped each other while we could.
I want to give the marriage another go. I am scared though things wont be different.
He hardly drinks anymore, he helps out with the kids all the time, he had shown me he appreciates the things I do.
We will of course be going to counselling.

But is it possible to have a marriage again? Any success stories from other IMs?
